Attach script at root CanvasLayer, so you can run DebugMenu.style

This fixes #15

Attached the script to the root CanvasLayer and re-attached the correct nodes.

Tested locally, it works as expected.

Thanks! Congratulations for your first merged pull request 🎉

I noticed this breaks _on_visibility_changed():

E 0:00:00:0835   debug_menu.gd:51 @ @style_setter(): Error calling from signal 'visibility_changed' to callable: 'Control::_on_visibility_changed': Method not found.
  <C++ Source>   core/object/object.cpp:1082 @ emit_signalp()
  <Stack Trace>  debug_menu.gd:51 @ @style_setter()
                 debug_menu.gd:140 @ _input()

Can you look into fixing this in a follow-up PR?

Alternatively, we can get rid of the entire method as it doesn't seem to do much nowadays. I've tried removing it locally and it doesn't seem to impact graphs negatively when you toggle them just after starting the project.

Ah good catch! I've fixed that in #17

The signal has been moved and I can see that it's being called and there's no more error.
