Media: Rename the `wp_ajax_save_attachment` action hook to `wp_ajax_save_attachment_updated`.

This changeset renames the `wp_ajax_save_attachment` action to `wp_ajax_save_attachment_updated` to avoid confusion with the similarly named `wp_ajax_save-attachment` action. This also add a dockblock note to indicate that when checking if an action is being done, `doing_action( 'wp_ajax_save-attachment' )` may be used if that is more convenient.

Follow-up to [55106].
