Now with the gpu_driver, the installing of the correct driver is
delegated to this role, which orchestrate the installing of one or more
drivers.

This refactoring of the role/testing, means that the roles don't run on
testing (intentionally), if a driver needs to be tested it will be added
but for now it's not really all that beneficial to keep this 30+ minutes
testing roles running just to test the packages existence.

It also simplifies the roles, and added as a dependency for steam which
is the main reason why these are needed to be installed (also better
hyprland animations, but that's not as crucial as steam failing without
the drivers).
