What changes did you make? (Give an overview)

This PR enables type assertions in .ts files via // $ExpectType comments. tests/lib/types/types.test.ts was imported from DefinitelyTyped and contains such comments, which are currently non-functional.

DefinitelyTyped uses dtslint to validate // $ExpectType comments, but dtslint assumes the same project structure and build tooling as DefinitelyTyped, so it does not integrate well with other projects like eslint. However, dtslint itself recommends using some other tools in order to just test types. One of those tools is eslint-plugin-expect-type, which recognizes // $ExpectType comments and integrates in eslint as a plugin. This is the solution I've ended up implemented in this PR.

Another option would be using an assertion library like expect-type or tsd instead of $ExpectType comments. These libraries provide type-checking at compile time, but have no knowledge of comments in code, so we would have to refactor those $ExpectType with other constructs provided by those libraries.

Is there anything you'd like reviewers to focus on?

I don't feel strongly about using a particular tool for type assertions. Shall we use eslint-plugin-expect-type as currently implemented in this PR or switch to something else?

I think it's fine to use the same checks to get started we can always evaluate other options later.

## PR Checklist - [X] Addresses an existing open issue: fixes #142 - [X] That issue was marked as [`status: accepting prs`](https://github.com/JoshuaKGoldberg/eslint-plugin-expect-type/issues?q=is%3Aopen+is%3Aissue+label%3A%22status%3A+accepting+prs%22) - [X] Steps in [CONTRIBUTING.md](https://github.com/JoshuaKGoldberg/eslint-plugin-expect-type/blob/main/.github/CONTRIBUTING.md) were taken ## Overview  This PR updates the `recommended` config to make it a valid flat config. Currently, the `recommended` config's `plugins` field is an array, and thus this config cannot be used in flat mode, where `plugins` is expected to be an object. It looks like the readme file already contains instructions for embedding the `recommended` config in a flat config file, but the `recommended` config itself hasn't been updated yet. ```js import expectType from "eslint-plugin-expect-type/configs/recommended"; export default [ // your other ESLint configurations expectType, ]; ``` I noticed this problem while working on eslint/eslint#18869.
