Editor warning for non-Node Autoload scripts

[archiebaldry]

I recently ran into an issue where my Autoload script wasn't working as expected. This was because I had made the script extend from the Object class and not the Node class (or a derivative of Node). I think the editor should give some kind of warning when trying to use a non-Node script as an Autoload. Here's a relevant Reddit post on r/godot. Please forgive me if I have misunderstood how Autoload works!

This suggestion may be better suited in the Editor category, but I'll leave it here for now. Please feel free to move it if required! :)

This may be intrinsically solved by godotengine/godot#81886 and been already proposed in #7710 , because all scene nodes inherit from Node.
