Desktop config updates

Programs Added (off the top of my head):
    - spotify
    - printer stuff
    Files Added:
    - print.nix
    Important Changes:
    - Lowered linux kernel version on desktop to 6.6 as the upstream
      kernel was causing the system to restart spontaneously - most
      likely a bug with Gigabyte Z790 UD boards. The t480 config still
      uses the upstream kernel.
