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

    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.
