* Throw error if res is accessed after gSSP returns
Currently it's possible to access the `ServerResponse` through `context.res`
in `getServerSideProps()`. If one was to store that response and mutate
its headers or status code after gSSP returns (e.g. during rendering), it
would currently happen to work because of when headers are sent. However,
this is an anti-pattern that relies an implementation detail of the framework
and shouldn't be allowed. This will be particularly important once Next.js
starts to support basic streaming (two-part flush: routing then data) because
then the headers will be sent as soon as gSSP returns, which explicitly breaks
this pattern.
With this commit, the framework now throws an error in development mode if
the ServerResponse is accessed after gSSP returns.
* fixup! Throw error if res is accessed after gSSP returns
I also removed the custom server link here, because I think it's making too strong of a correlation between custom server and Node.js server using `next start`, which aren't the same.
This is a follow-up to https://github.com/vercel/next.js/pull/29060 removing the `test_macos` workflow since it is redundant to run these tests in macOS as it should be very unlikely the tests fail in the mac environment but pass in the ubuntu environment. It also seems the snapshot tests are incorrect inside of the GitHub actions macOS environment so these tests will not work correctly anyways.
Updates the `with-google-tag-manager` to use Next.js' Script component with strategy set to `afterInteractive`

I imported a bunch of old markdown posts to the blog-starter example but some of the post metadata was not returned by the API in the example code.
For example, having `published: false` in post metadata was not returned in the item fields.
The problem was in check:
```
if (data[field]) {
items[field] = data[field]
}
```
This rejects all falsy values in addition to fields that are not set. Checking only for `undefined` should fix this issue.
I didn't find existing integration tests for the blog example nor an issue describing this problem.

Use `Writable` instead of `Observable` and remove the `zen-observable` dependencies. I initially opted to use `Observable` for simplicity and fast iteration, but we should really just use `Writable` directly (or some other stream in the future).
React's streaming SSR has some [specific requirements](https://github.com/reactwg/react-18/discussions/66#discussioncomment-944266) on the stream API. Rather than trying to also squeeze a `Readable` in here, which might be more standard for node apps, I've just followed React's lead. By limiting ourselves to just `Writable`, it ought to be easier to adopt a different stream type in the future if desired.
The React `pipeToNodeWritable` API requires us to pass a stream immediately, but we don't actually have a `ServerResponse` to give it until `RenderResult.pipe(...)` is called later. For that reason, we pass React a `Writable` that we will simply forward to `res` later. This mechanism of deferring is `NodeWritablePiper`, which is just a function that can be called with `ServerResponse` (or another `Writable`, as we now do to render to string for static results) to have content written to it. `NodeWritablePiper` takes a `next` argument so that we can chain both synchronous and asynchronous pipers together.
Also does some clean up and adds another streaming test for backpressure.
In a previous PR, `getServerSideProps` was altered to support returning
`props` as a promise. This change updates the TS types to permit promises
as well, so you can write type `GetServerSideProps<Props>` instead of
`GetServerSideProps<Promise<Props>>`. e.g.:
```typescript
type Props = {
data: string
}
export const getServerSideProps: GetServerSideProps<Props> = async (
context
) => {
return {
props: (async function () {
return { data: 'some data' }
})(),
}
}
```

This ensures we have the correct `cache-control` header when `revalidate` is used with `notFound: true` on `getStaticProps` or `getServerSideProps` pages.

I updated rust dependencies and node dependencies.
We're no longer currently planning on supporting caching for dynamic responses, so we can do some cleaning & simplification:
* Multiplexing can be removed since we only ever subscribe once (via `RenderResult.pipe`, described below)
* `RenderResult.toUnchunkedString` can become synchronous since static responses are never chunked
* `RenderResult.forEach` can become `RenderResult.pipe` which helps encapsulate some of the details of `RenderResult`
This applies the fix from the awesome investigation done in https://github.com/vercel/next.js/issues/28797 by @jayphelps and adds a test to ensure this is working as expected. It seems that the `route-loader` has a race condition while prefetching and if a script is executed before we have created a current "future" entry to resolve the entry stays in a pending state causing routes to hang so this handles the condition by ensuring pending/errored entries do not stay around.

Updates the React 18 concurrent tests to support streaming, by using webdriver (instead of cheerio) to support dynamic updates, and being more explicit about SSR vs. hydrated content.
Also enables streaming support by setting `supportsDynamicHTML: true` in `pipe(...)` for non-bot user agents.
Earlier it was:
```bash
npx create-next-app --example with-eslint with-eslint
# or
yarn create next-app --example with-eslint with-eslint
```
It was confusing for me,
as i couldn't identify which one is *example-name* and which one is *folder-name* (for *with-eslint*).
I checked other example folders and was able to digest the stuff.
But if a new programmer comes who is not familiar with next/npx,
this could have took some time to understand.
And Hence i modified the cmd it to the below, for better understanding:
```bash
npx create-next-app --example with-eslint with-eslint-app
# or
yarn create next-app --example with-eslint with-eslint-app
```

This ensures we trim test output that will exceed the amount that can be shown in GitHub actions so that we can still see which tests failed instead of un-helpful test logs.
Updating @react-three/drei from 4.x to 7.x
I was having problems using this example and realized that it was caused by the "old" version of the lib.
Also updating @react-three/fiber and next to latest.
