Plugin created in addons sub-subfolder is detected, but class_name nodes & resources don't show in Create New Node/Resource dialogue

Issue description

Custom (class_name) nodes & resources don't show up in Create in New Node/Resource dialogues.

This came up because I was looking at Godot Project Manager which uses NPM as a the packager and delivery mechanism. With NPM we can use scoped names like @scope/package and they get installed at addons/@scope/package.

They're detected by Godot just fine, it's just that the custom nodes and resources don't appear in the dialogues as mentioned.

Steps to reproduce

• Top Level plugin is in addons/top_level
• Nested Level plugin is in addons/@scope/nested_level

Open the attached project and see that:

• Plugins ON => TopLevel* visible, NestedLevel* not visible
• Plugins OFF => TopLevel* not visible, NestedLevel* not visible

in Create New Node/Resource.

Furthermore, it seems that we have access to the classes in code even if the plugins are ON or OFF. I thought they should be registered globally only when plugins are ON.

godot4.1 seems to be simply hanging when addons exist now
