### Update
We removed the `<head>` element checking for root layout in #41621. Since we also need `<head>` for preload in the future, and also css-in-js will require that. We're adding back the `head` element checking to make sure user always provide valid root layout including it.
### Issue
An issue was reported [here](https://github.com/mui/material-ui/issues/34905#issuecomment-1331945868) that the Emotion/MUI site was suffering from FOUC.
After an inspection, I noticed that the SSRed HTML didn't contain the inserted styles at all - despite them being inserted through `useServerInsertedHTML`. I managed to debug it down and discovered that their layout was missing `<head></head>` and thus the stream transformer skipped the insertion altogether cause of this check:
fbc98abab3/packages/next/server/node-web-streams-helper.ts (L177-L183)
I've figured that at the very least we could surface this as a console error in development to nudge the user to fix the missing `<head/>`

In #42987 we added support for `transpilePackages` in `next/jest`, but
the pattern is not functioning how we would expect here, and as a result
all modules from `node_modules` are getting transformed. File patterns
that should not be transformed should match, but due to the trailing
`/`, no packages are matching.
Currently (no match, incorrectly gets transformed):

With this fix (matches, correctly does not get transformed):
https://regexr.com/73fvr
As far as I can tell, the `pnpm` pattern is being generated correctly.
@balazsorban44 I wasn't sure the best way to test this one, let me know
if you've got an idea. 🙏

Added an image gallery example using Next.js and Cloudinary.
Edit: This is now ready to ship!

Fixes pnpm w/ example being the only test outside the test suite.
Before:
```ts
describe('create next app', () => {
// ...
})
it('should infer pnpm as the package manager with example', () => { ... })
```
After:
```ts
describe('create next app', () => {
// ...
it('should infer pnpm as the package manager with example', () => { ... })
})
```

This PR is a follow-up PR of [PR
43304](https://github.com/vercel/next.js/pull/43304).
This fix works by checking if the page is listed in
middleware-manifest.json's functions, if true then skip the
handleTraceFiles process. This also fixes the two issues aforementioned
by copying files listed in middleware-manifest.json for those pages.

This PR remove `React.useState()` from the `next/image` component. It
was only used in the `onError` case and it was causing Safari to become
very slow when there were many images on the same page. We were seeing
1s delay blocking the main thread when there were about 350 images on
the same page. Chrome and Firefox were not slow.
The **Output File Tracing** page mentioned that `publicRuntimeConfig`
and `serverRuntimeConfig` are now legacy and does not work with Output
File Tracing (they are _inlined at build-time_ instead of being set at
runtime, the way it is supposed to work).

However, the Runtime Config page itself does not mention this at all.
This led me into a wrong path for a while.

Simplified the example to just the specific feature, and converted to TypeScript.
- `node-fetch@2` is either polyfilled by Next.js or a peerDep of `@vercel/fetch`, I can't quite tell, but either way it can be removed from the dependencies.

Related to the build failure from #41931
We need to bundle `next/head` so that it can appear in the
flight-client-manifest, so we changed the behavior to not treat it as
non externals.

Currently the generated matcher will be `"regexp": "^\(group\)/group$"` for groups which doesn't match the correct route. This is somehow related to #43458, but it only fixes the problem partially. Some other changes need to be made in the build process.

This PR adds an example `yarn up` command to bump the relevant dependencies when using yarn berry for the Next 12 to Next 13 upgrade. One thing to possibly note is that `yarn up` is not scoped to a single workspace like `yarn upgrade` in classic - to get around this when in multiple workspaces, the `-i/--interactive` flag can be passed.
**Update** - can upgrade dependencies in both yarn classic/berry using `yarn add ...@latest`, this may be more straight forward than having two separate commands.

This PR adds proper cleanup step for ~`edgeServerModuleIds`,
`serverModuleIds` and~ `flightCSSManifest`, which was previously
missing. Otherwise it will grow indefinitely during development.
