info-overview: show only the GNOME major version
What we have is the GNOME Shell version, which is NOT the same as the GNOME version. I thought it'd be nicest to rename this to "GNOME Shell Version" but it seems we want to keep that as an internal codename not exposed to users. So instead, let's just show only the major version, which should hopefully match. This is very generic and much less useful but I don't see a better solution.
