Replace outdated Prettier settings with recommended ones (#43756)

Summary:
The React Native ESLint preset currently endorses the Prettier integration that is [explicitly recommended against by Pretier itself](https://prettier.io/docs/en/integrating-with-linters). Notice the difference between these two packages:

- `eslint-config-prettier` is the config that turns off all formatting rules. It's **recommended by Prettier** to be used together with Prettier. You'd still use Prettier itself to actually do the formatting.
- `eslint-plugin-prettier` is a legacy plugin developed a long time ago and that predates most modern Prettier integrations. It runs Prettier as if it were an ESLint rule, applies formatting on `--fix`, and **is not recommended**.

Unfortunately, RN uses the latter one (and always has).

This PR removes `eslint-plugin-prettier` and instead enables `eslint-config-prettier`, as recommended by Prettier.

As a consequence, you'll no longer see squiggly lines in your editor for stuff that isn't actually errors:

As another consequence, **you'll have to set up your own Prettier step in your pipeline**.

For example, if your precommit hook only contained `eslint --fix`, you'll now also need to run `prettier --write` there as well. Similarly, if you want Prettier to fail CI, you'd need to find where you call `eslint` and also do `prettier --check` there.

Here's an example for how to do it: bluesky-social/social-app#3373
