update eslint config (#53637)
## Fixing a bug
- I checked the eslint config and found that override property is not supposed to be inside another override property.
- I couldn't checked the entire file as it was a big config file, but I guess it was supposed to be a part of global overrides array of eslint.

chore: enable typescript-eslint's recommended and stylistic configs internally (#52948)
Spinning out from #37151 and my draft PR #52845, this enables the two
basic recommended rulesets from
[typescript-eslint](https://typescript-eslint.io) for the Next.js
monorepo source code:

*
[`plugin:@typescript-eslint/recommended`](https://typescript-eslint.io/linting/configs#recommended):
Our base recommended rules that detect common bugs or _(non-stylistic)_
TypeScript bad practices
*
[`plugin:@typescript-eslint/stylistic`](https://typescript-eslint.io/linting/configs#stylistic):
Our base starting stylistic recommended for keeping codebases visually
consistent and avoiding out-of-practice visual constructs

The process I used is pretty standard (see
https://github.com/typescript-eslint/typescript-eslint/issues/6760 for
other repos it was done on):

1. Enable those base recommended presets
2. Remove any rule settings that are now redundant
3. Reconfigure any rule whose default settings didn't seem to make sense
for this codebase
4. Add a `// Todo: ...` comment, and under it, add a disable for any
rule that immediately reported a lot of complaints

Note that this only enables the presets internally. It doesn't impact
what end-users of published packages such as Next.js or
`create-next-app` experience. That's a separate task in #52845.

I also didn't fix any existing warning from the `canary` branch. Would
you like me to do that? My preference would be a separate PR to get it
in more quickly.

Any code changes are commented inline.

Update MetadataRoute to namespace (#47674)
### What?

Followup for #47630 , use ts namespace to group MetadataRoute.

`MetadataRoute['xxx']` -> `MetadataRoute.xxx`

### Why?

namespace is convenient to write for these grouped types such as
`MetadataRoute.Robots`. And `MetadataRoute` itself is not actually a
type. So it can be conveniently typed by ts users.

### How?

Closes NEXT-912

Hybrid App Hooks Support (#41767)
This adapts the new client hooks of `usePathname`, `useSearchParams`,
and `useRouter` to work within the `pages/` directory to aid users
attempting to migrate shared components over to the `app/` directory.

> **Exception:**
> When the pages router is not ready, `useSearchParams` will return an
empty `URLSearchParams`. This mirrors the behavior seen in the `pages/`
directory today in that `router.query` is not available until the client
hydrates.

This also adds a new option for `useRouter` to bring it line with the
correct typings with the app directory. By default, calling
`useRouter()` will return the type `NextRouter | null` to represent what
you get when you call it from a component originating from the app
directory. If you want to instead force it to return `NextRouter` as it
does today, you can pass a boolean into the `useRouter` call as such:

```ts
const router = useRouter()     // typeof router === NextRouter | null
const router = useRouter(true) // typeof router === NextRouter
```

This change is designed to ease the incremental adoption of app.

Enable import assertion syntax parsing (#33750)
## Feature

Enable import assertion syntax parsing for ecmascript/typescript. Since webpack has already supported it, enable import assertion parsing and leave them to webpack to handle

#### Upgration
* tooling: `@swc/core`, `@swc/cli`, prettier to support importAssertion related flags
* typescript related: `typescript` >= 4.5
* babel related: `@babel/plugin-syntax-import-assertions`
* lint parser: `@typescript-eslint/parser`
