Provide language fallback to country official language for labels if the monument doesn't have a label in the user's language

E.g there are 1000s of monuments in Paris without an English language label because there is no English name for the site. English uses the French name for the buildings, with some exceptions for very famous places like Eiffel Tower rather than Tour Eiffel. It is not correct to add the French name to the English label in Wikidata because it isn't an English name, so if Wikidata stores data correctly the sites will never have an English label. This is true for a lot of monuments in a lot of cities.

One way to address this in Monumental would be to provide a language fallback to the label or labels for the official language or languages for that country. This gets a bit messy in places like Belgium, India or South Africa where there are more than one official language. One solution to this would be to fallback to show the language with the most speakers for that region and then fallback again to second most spoken if that is not available, etc etc.
