Workspace config: menu_item_extras.utility config breaks /admin/config

Problem/Motivation

The config menu_item_extras.utility config of the menu_item_extras module breaks the /admin/config page when wse_config is active. This basically happens, because menu_item_extras_entity_type_build() is loading the menu_item_extras.utility config which will trigger wse_config which uses entity queries which will again trigger menu_item_extras_entity_type_build() etc.

Steps to reproduce

On Vanilla Drupal 9:

1. Install menu_item_extras and wse_config modules
2. Navigate to /admin/config
3. An infinite loop will occur

Proposed resolution

Ignore the menu_item_extras.utility config in WseConfigSubscriber::onWseConfigOptOut() . This config doesn't need to be overridden inside workspaces at this point. Should that become necessary we can look into it in more detail.
