NOTE: This ticket is a "maybe." There will first need to be a product/UX investigation to determine if wish #4 is complete, from a user perspective, or if additional work is required.
As a Wikisource user, I want the team to investigate the "Interlanguage link support via Wikidata" wish, so they can determine if the wish is done or if there is any more work to do.
**Background:** In the [[ https://meta.wikimedia.org/wiki/Community_Wishlist_Survey_2020/Results | 2020 Community Wishlist Survey ]], the [[ https://meta.wikimedia.org/wiki/Community_Wishlist_Survey_2020/Wikisource/Inter-language_link_support_via_Wikidata | #4 wish ]] was "Interlanguage link support via Wikidata." This work may be complete via [[ https://www.mediawiki.org/wiki/Extension:Wikisource | Extension:Wikisource ]]. We may want to examine the current status and determine if there is any more work to do.

**Acceptance Criteria:**
