Subject: [PATCH] gtksourceview4: Backport Nix syntax highlighting support

This brings the support to editors that haven't ported to GTK4.

I am looking at https://gitlab.gnome.org/GNOME/gtksourceview/-/tree/master/data/language-specs
and most files are not changed for six years so I assume no breaking changes for these specs
are made so far.
