Code Modernization: Use array_any() in WP_REST_Comments_Controller.

This commit replaces a `foreach` loop in `::check_post_type_supports_notes()` that iterates the editor supports, returns `true` as soon as an element has non-empty notes, and otherwise falls through to `false`. That is exactly what PHP 8.4's `array_any()` expresses in a single, more readable call.

WordPress core includes a polyfill for `array_any()` on PHP < 8.4 as of WordPress 6.8, so the change works on every supported PHP version without raising the minimum requirement.

Follow-up to [59783], [62550], [62553].

Props Soean.
See #65519.
