Because of [hardcoded terminals in
glib](https://gitlab.gnome.org/GNOME/glib/-/blob/main/gio/gdesktopappinfo.c#L2755)
the previous fix still doesn't work well with Alacritty and Kitty.
Using our `omarchy-launch-terminal` aliased to `xdg-terminal-exec` does
the trick and doesn't introduce any new dependencies or rely on a lib
that isn't stable.
