Rewrite entity_display_build_alter hook to simplify logic and make it compatible with layout builder. Displays a placeholder when viewed in layout builder. Leaves the field display as is (empty) if the user is logged in and doesn't have permission to create reviews. Removed redundant check for existing user reviews. There are always no reviews for the product. Only directs anonymous users to login page, not everyone without create access.
