Issue description

In godot 4.3 when we used register_internal_class to register a class it was not getting exposed and it was not possible to create or view it in new node creation dialog. In Godot 4.5 it doesn't matter if class is registered with internal or regular p_exposed doesn't seem working.

Steps to reproduce

1. Create a class
2. Register using register_internal_class

ClassDB::register_internal_class<MyNode>();

3. Open editor, Open add node dialog and search MyNode and it will be there.
