We found a case where 14.0.0 breaking with private class methods, such
as:
```js
class C {
#x() { return 42; }
x() {
return this.#x();
}
}
```
This feature was introduced in Node.js 14.6.0, so we can bump the
minimum version.
See https://node.green
Next.js 13 will require React 18.
In this PR I've only updated the peerDependency and removed the test runs in GH actions. Further cleanup will follow later, this allows us to remove the code supporting it later.

This PR adds a new configure property, `images.loaderFile` that allow
you to define a path to a file with an exported image loader function.
This is useful when migrating from `next/legacy/image` to `next/image`
because it lets you configure the loader for every instance of
`next/image` once, similar to the legacy "built-in loaders".

I stumbled upon a lack of clarity when using `<Link />` where I believed it didn't execute the server methods before navigation. This change makes it a bit more clear

Remove `browsersListForSwc` since it is enabled by default now, and disable `legacyBrowsers` by default.
This PR also bumps the default browserslist to the following:
- Chrome 64+
- Edge 79+
- Firefox 67+
- Opera 51+
- Safari 12+

- Closes#33227

The `target: serverless` config was deprecated a year ago starting in
[Next.js 12](https://nextjs.org/blog/next-12).
Tests were disabled in #41252 so we can now remove `target: serverless`
and all usage of `target` in `next.config.js`.

- Enable newNextLinkBehavior. See #36436
- Run next/link codemod on test suite
Note that from when this lands on apps trying canary will need to run
the new-link codemod in order to upgrade.
Ideally we have to detect `<a>` while rendering the new link and warn
for it.

This PR updates the docs for the following code change:
- #41399
There are a few updates here:
- [x] Update docs
- [x] Update links to docs inside component
- [x] Update examples
- [x] Fix corner cases in codemod
MDX no longer supports GitHub flavored markdown (GFM) by default since v2, instead requiring a plugin: https://mdxjs.com/guides/gfm/
Since GFM is extremely popular (for example, you need it if you want to use markdown tables), this change paves the cow path, making it clear that next.config.mjs is now supported and allows you to import remark-gfm.

This adds two codemods for `next/image`.
The first codemod a safe solution to upgrade from 12 to 13 by swapping
to `next/legacy/image`.
The second codemod is an experimental solution that attempts to automate
the [migration
guide](https://nextjs.org/docs/api-reference/next/future/image#migration).

This commit implements the main proposal presented in
https://github.com/vercel/next.js/issues/39241
to add attribution to web vitals.
Attribution adds more specific debugging info to web vitals,
for example in the case of Cumulative Layout Shift (CLS),
we might want to know
> What's the first element that shifted when the single largest layout shift occurred?
on in the case of Largest Contentful Paint (LCP),
> What's the element corresponding to the LCP for the page?
> If it is an image, what's the URL of the image resource?
Attribution is *disabled* by default because it could potentially
generate a lot data and overwhelm the RUM backend.
It is enabled *per metric* (LCP, FCP, CLS, etc)
As part of this change, `web-vitals` has been upgraded to v3.0.0
This version contains minor bug fixes, please see changelog at

The docs have a misleading `console.log` output for the input
`process.env` that doesn't display all the variables on edge runtime.
The example shows an output of a supposed object with all the
environment variables, but it does this when logging a specific
variable.

Reverts vercel/next.js#40016.
`pageExtensions` is not frequently used – as is mostly a workaround
until the Layouts RFC lands. Thus, it doesn't make sense to place a note
on the Middleware page and expect readers to need to connect the dots
and understand `pageExtensions`.
Further, the example docs linked could be more specific about Middleware
to prevent this confusion. I will also make that change here.

Made an addition to the version history within the Script component
docs. In the docs there are examples where the Script component is being
used within a _document.js/tsx file, but it does not get mentioned that
this is only supported from version 12.2.2 onwards.
