Remove jQuery .map() and enable eslint rules for it (#29272)

- Use case in `repo-commit` was tested until the point where the POST
request was sent with the same payload.
- Use case in `repo-legacy` was tested completely with comment editing.
- `jquery/no-fade` was disabled as well to stay in sync with
`no-jquery/no-fade`, had no violations.
