feat(users/Profpatsch): dbus service for changing monitor brightness r/9003

This simple dbus service will use the ddcci interfaces to change
brightness for both the internal and external monitor (roughly in
sync).

Currently in the alacritty-change-color-scheme script because I’m lazy
and still experimenting.
