Editor: fix contributor "Slow down" message when updating Notes quickly.

Fix an issue where contributors’ notes edits were throttled. Notes are internal and from trusted users, they do not need throttling. 

Skip calling wp_allow_comment for notes in WP_REST_Comments_Controller::create_item. As a result the pre_comment_approved hook is also not fired for notes. 

Fixes WordPress/gutenberg#72892 where the issue was originally reported.

Props adamsilverstein, desrosj, wildworks, mamaduka.
Fixes #64199.
