games: route every Steam-launched window to workspace 8

Hyprland's class rules only catch Proton games (steam_app_N) and
whatever else is listed by name, so a non-Steam shortcut, here a GOG
Ren'Py build with its own class, opened on the current workspace.
Steam sets SteamGameId in the environment of everything it launches,
native, Proton and shortcuts alike, so on openwindow the shell looks up
the window's pid and moves it when /proc/<pid>/environ carries that
variable. Checked with the shortcut that motivated it.

+Every game window lands on workspace 8, however it was started. Steam
+sets `SteamGameId` in the environment of every game it runs, native,
