prs`](https://github.com/JoshuaKGoldberg/create-typescript-app/issues?q=is%3Aopen+is%3Aissue+label%3A%22status%3A+accepting+prs%22)
- [x] Steps in

## Overview

Adds:

- `--exclude-lint-deprecation`
- `--exclude-lint-eslint`
- `--exclude-lint-jsdoc`
- `--exclude-lint-regex`
- `--exclude-lint-strict`
- `--exclude-lint-stylistic`

Assorted cleanups:

* Removes `eslint-config-prettier` since I believe none of the
recommended configs include rules impacted by it (yay!)
* Removes `eslint-plugin-import` as TypeScript's `"moduleResolution":
"NodeNext"` will report on a missing file extension in an import
* As of eslint-community/eslint-plugin-n#24 I
don't think `n/no-missing-import` is buggy enough to need to be disabled
* eslint-community/eslint-plugin-n#84 is still
in effect, but this template doesn't use `paths`.
* Removes the ESLint config comment now that most users are on a simpler
"common" config
* Finally add some high-level unit testing for `createESLintRC` to help
validate the changes
