Expand and clean up Arch GNOME packages, remove alacritty from Arch

- arch_desktop_gnome_packages: add full GNOME app suite (baobab, gnome-console,
  loupe, papers, showtime, snapshot, sushi, gvfs backends, etc.), sort
  alphabetically, remove duplicates already in arch_packages_base
  (gnome-keyring, gvfs, gvfs-mtp, gvfs-smb, simple-scan)
- Remove alacritty from arch_profile_packages; move alacritty config and
  directory creation to Void-only (profile_desktop_i3 / desktop_void_dotfiles)
- Enable emacs user service via ansible.builtin.systemd (scope: user)
  instead of a manual symlink
