It seems like $target defined by parameter $target on line 42 can also be of type object<Wikibase\DataModel\SiteLink>; however, Wikibase\Api\Service\AliasGroupSetter::getEntityIdentifierFromTarget() does only seem to accept object<Wikibase\DataModel\Entity\EntityId>|object<Wikibase\DataModel\Entity\Item>|object<Wikibase\DataModel\Entity\Property>, maybe add an additional type check?
