[Enhancement]: Add "proton-game" windowrule for launchers like Heroic

### Already reported ? * - [x] I have searched the existing open and closed request. ### Description Currently in `~/.config/hypr/configs/WindowRules.conf` there are window rules for Heroic, steam (gamescope/appid), and Lutris for games+gamestore tags. Using these tags to set application management makes it a lot easier, but with the current rules only steam games fall under the "games" tag which leaves management for games under "Heroic" and "Lutris" for the user to figure out, which is relatively easy with `hyprctl clients` however I think this suggestion should be a default configuration. ### Proposed Solution Since majority use cases call for proton over wine when running games, I think adding something like `windowrule = match:xdg_tag ^(proton-game)$, tag +games` would benefit most users as it seems to be a catch all for Heroic and Lutris (possibly other launchers too), rather than supporting two launchers with rules and ironically not supporting it's games like steams `^(steam_app_\\d+)$,` tag.
