Background Loading is outdated

[Ansraer]

Your Godot version:
4.0

Issue description:
As far as I can tell reduz replaced the entire Interactive Loading system with godotengine/godot#36640.
Instead of ResourceLoader::load_interactive users should now use:

Error ResourceLoader.load_threaded_request(path: String, type_hint: String = "", use_sub_threads: bool = false)
ThreadLoadStatus ResourceLoader.load_threaded_get_status(path: String, r_progress: Array = [  ] ) 
Resource ResourceLoader.load_threaded_get(path: String)

However, the documentation hasn't yet been updated to reflect this change.
