Subject: [PATCH] build: Add support for validating appdata versions

This will avoid old dates from being mentioned in the appdata file, as
happened in evince.

This requires a version of appstream-util with the get-latest-version
command:
https://github.com/hughsie/appstream-glib/pull/468

See https://gitlab.gnome.org/GNOME/evince/-/issues/1950
