Direct Steam Store page download for Steam Deck

[MXNPD]

As the title suggests, having a dedicated page on the Steam Store to download Moonlight (Mainly for the Steam Deck) would be a fantastic addition that I think most Deck users would appreciate, this was we don't have to rely on the flatpak version of it, and there could be specific things included to the Steam Deck version (what, I am not sure, it is fine as is, but maybe down the line)
