[mediawiki/extensions/ArticleGuidance@master] wbgetentities: use languagefallback=1

Mixed results. A search can return some items with Hindi labels and some without. The message should only appear when at least one item actually falls back, and it should make clear that *some* names aren't available, not all of them.

It is not always obvious if the label is missing for a language. Some items use the lang code "mul" to indicate that a label can be used for any language unless explicitly redefined. Is this case, we don't know if it should be defined.

We could use the following rule: when asking for label in language x and receiving label in language mul: the label is not missing. When asking for language X and receiving Y: the label is missing.

Fallback chain. Rather than jumping straight to English, walk the MediaWiki standard language fallback chain (so e.g. a Hindi user might see Sanskrit before English, depending on the wiki's configuration).

When calling the wikidata API to get labels and description, we are enabling the language fallback feature. As far as I understand it is using the standard MediaWiki language fallback system internally.

Message string (placeholder): "Hindi names aren't available yet for some items; showing those in another language."

Using language name inside of a message is tricky. If you can think of an alternative that doesn't include "Hindi" that would be preferred.

Working as expected, moving it to product signoff
