feat(pkgs/Profpatsch/alacritty): register color dbus interface r/8997

Adds a simple-stupid dbus interface for this daemon which allows
on-the-fly changing of the alacritty color scheme.

Example call:

```
busctl --user call de.profpatsch.alacritty.ColorScheme \
 /de/profpatsch/alacritty/ColorScheme \
 de.profpatsch.alacritty.ColorScheme \
 SetColorScheme s 'prefer-dark'
```
