When you're trying to migrate an application from `pages/` to `app/`,
you'll need to access data like search parameters and the pathname in a
way that lets you migrate safely.
This adds support for dynamic typing of some of those exported functions
from `next/navigation`, namely `useSearchParams` and `usePathname`.
Currently, `searchParams` can’t be known when prerendering if the page
doesn’t use [Server-side
Rendering](https://nextjs.org/docs/basic-features/data-fetching/get-server-side-props)
in the `pages/` directory. `pathname` can’t be known during prerendering
if the page is a fallback page or has been automatically statically
optimized when accessed from `pages/`.
To make migraitons easier, this adds a new feature to `next dev` that
will automatically add the correct types for `next/navigation`. It does
this by checking if you have both a `app/` and `pages/` directory. If it
detects you have a `app/` directory, it will also enable the suggested
Typescript feature,
[`structNullChecks`](https://www.typescriptlang.org/tsconfig#strictNullChecks)
which will warn developers when trying to access a value that may be
`null`.

Follow-up to https://github.com/vercel/next.js/pull/37902 this moves the reference to avoid a change in `next-env.d.ts`. Also updates our doc note on the `next-env.d.ts` file to be more explicit about it being ignored.

## Feature
- [ ] Implements an existing feature request or RFC. Make sure the feature request has been accepted for implementation before opening a PR.

## Documentation / Examples
- [x] Make sure the linting passes by running `pnpm lint`
- [ ] The examples guidelines are followed from [our contributing doc](https://github.com/vercel/next.js/blob/canary/contributing.md#adding-examples)
This ensures we expose the `styled-jsx` types correctly even when the package is not hoisted from next's `node_modules` e.g. when using `pnpm`. We had an existing test that covered this although it installed `styled-jsx` at the top-level as a workaround so the test has been updated to remove this workaround.
