Wrong state_name_type for France

[bojanz]

France currently inherits the default (ZZ) state_name_type of "province".
But the correct state_name_type should be "region", as explained by @comxd in commerceguys/addressing#161

Also, Google Maps API's provide a "region" for the "administrative_area_level_1" field. (@see https://developers.google.com/maps/documentation/javascript/geocoding?hl=fr#GeocodingAddressTypes)

This isn't noticeable because there are no regions defined for France by default, but there's no reason to show a wrong label when people do provide their own region list (in libraries that allow that).
