CI: fix some workflow issues (#371)

* CI: update NEWS which caused some workflow issues

* CI: disable gdk-pixbuf-thumbnailer for meson workflows

 - gdk-pixbuf-thumbnailer is obsolete and should be replaced
   with glycin-thumbnailer

* meson: Only use girepository-2.0 if libpeas uses it too

Fixes header conflicts on systems where glib has girepository-2.0 but
libpeas still uses the old gobject-introspection-1.0 headers.
