Fixes users not being to switch to gaming mode when they have desktop autologin toggled
and should allow users to start gaming mode immediately after Steam has been updated
instead of having to reboot after setup (although this should be done regardless)
I started messing with systemd conditions to ensure that one ran before
the other and vice versa, but this is a whole lot simpler.
If Steam has updated, launch gamescope. If not, start to desktop
