Add reference to InputEventJoypadButton in _shortcut_input doc

[Chronos-W]

According to the fix in #66750, InputEventJoypadButton can now be used in _shortcut_input, but it looks like this info hasn't been added to the docs https://docs.godotengine.org/en/latest/classes/class_node.html#class-node-private-method-shortcut-input.

After this change, InputEventJoypadButton will be mentioned alongside the other InputEvents in this method's doc.

Note that information about this has already been added to https://docs.godotengine.org/en/latest/tutorials/inputs/inputevent.html#how-does-it-work.
