Prefer OSM over Wikidata for names in local language

[xkomczax]

Currently, OpenMapTiles prefers OSM over Wikidata if the local name variant is filled in - e.g. if there is a name:es filled in, it will be used for Spanish translation.

However, as @pnorman pointed out, in case there is only a name tag filled in and the object is located in Spain, the name:es tag is taken from Wikidata (even though we have a Spanish name in this case).
Example:

• OSM object in Spain with name tag (but name:es is missing): https://www.openstreetmap.org/relation/12589720
• Spanish "translation" (taken from Wikidata): https://osm.openmaptiles.org/?locale=es#map=19/41.31943/-6.39589&layers=V
• Wikidata entry: https://www.wikidata.org/wiki/Q101997823

It would be great if the name tag is automatically used for name:es in Spain (if the name:es tag is missing), name:fr in France, etc.

It would be great if the name tag is automatically used for name:es in Spain (if the name:es tag is missing), name:fr in France, etc.

This approach would require developing a mapping from regions to presumed languages, which is not necessarily straightforward.
