When Content Translation connects articles in Wikidata, it should also add a label.
This arrived as a suggestion from a Content Translation user, but thinking more deeply, maybe it should be built into Wikidata, and the wb.PageConnector library, which creates the connection, should also auto-add a label? Content Translation is not really unique.
We do this when creating a new item, but don't dare otherwise (in Wikibase client), because any label is better than none if there aren't any, yet we don't want to interfere with the community on Wikidata.
Little remark, because in wikidata we cannot have the same label and description so if it exist label AAA without desctiption, you cannot only remove (BBB), from AAA (BBB) because it will be the same description and label like the existing item
