NOTIFICATION_WM_CLOSE_REQUEST is incorrectly described to exist in MainLoop by some documentation.

[droqen]

Your Godot version: v4.2.stable.official

Issue description: MainLoop.NOTIFICATION_WM_QUIT_REQUEST and MainLoop.NOTIFICATION_WM_CLOSE_REQUEST are referenced, but neither one works (despite the phrasing "you can remove the MainLoop. prefix" implying that it is optional); the only one that works is NOTIFICATION_WM_CLOSE_REQUEST.

MainLoop class documentation correctly excludes both but does not direct the user to the correct location of these constants; maybe they were removed from the class unintentionally?

URL to the documentation page: https://docs.godotengine.org/en/stable/tutorials/migrating/upgrading_to_godot_4.html

MainLoop's NOTIFICATION_ constants were duplicated to Node which means you can remove the MainLoop. prefix when referencing them. MainLoop's NOTIFICATION_WM_QUIT_REQUEST is now NOTIFICATION_WM_CLOSE_REQUEST.
