_disable_content_editor_for_navigation_post_type() │ WP 5.9.0

This callback disables the content editor for wp_navigation type posts. Content editor cannot handle wp_navigation type posts correctly. We cannot disable the "editor" feature in the wp_navigation's CPT definition because it disables the ability to save navigation blocks via REST API.
