feat(pkgs/Profpatsch/alacritty): init dark mode dbus daemon r/8996

A simple dbus daemon that writes the alacritty config to
`~/.config/alacritty/alacritty-colors-autogen.toml` on startup and
whenever a change between dark/light mode is requested.

Alacritty only implements an config file isync watcher, no SIGHUP
handler or similar, so we have to actually write the config file lol.

This is all a little glue-y, but idk, whatever.
