Update language-data from upstream

Add:
* Acholi (ach)
* Lango (laj)
* Mansi (mns)

Update autonym:
* Komering (kge, kge-arab)

Also set up Manchu (mnc) as:
* mnc (in practice Latin script)
* mnc-latn (redirect to mnc)
* mnc-mong (Mongolian/Manchu script)
This may be changed later, but for now,
this is the situtation in core MediaWiki,
so working with that.

Updating to
wikimedia/language-data@5fee9a3
