Subject: [PATCH] Add Steam+DpadUP binding (#8)

* Add Steam+DpadUP binding [ci skip]

Windows on SteamDeck generally needs a hotkey available to use with upscaling applications as many games crash when attempting to render exclusive fullscreen.

Added the following binding:
- Steam + DPadUP = Ctrl+Alt+U

* Include new Steam+DPadUP binding in readme

Added keybind to table list. Included instructions on how the binding can be used to set up a full screen scaling toggle.
