The `NodeCategory` system is not used by Blender anymore for a couple years already. Instead of using an additional abstraction layer, we now just use a normal menu. One benefit of the `NodeCategory` system was that it could be used to populate the search. However, the search is now directly populated from the menu anyway. Fixes #115746.
