[tracker/wip/carlosg/glib2-xref] ci: Download and install glib2-doc manually

[Carlos Garnacho <carlosg src gnome org>]

commit e4ddc32c81327d2ad5b9d16339b10184d235f03a
Author: Carlos Garnacho <carlosg gnome org>

    ci: Download and install glib2-doc manually
    
    For some reason, dnf eats /usr/share/gtk-doc away in containers.
    We need the glib2 documentation for online docs to be found, and
    cross referencing to work.
