Reason: PageLanguageApi's functionality is available in MediaWiki core since 1.29. Thus, this extension should be archived.
- [x] Archive on `mediawiki.org` ( https://www.mediawiki.org/wiki/Extension:PageLanguageApi )
- [ ] Remove from `mediawiki/extensions` ( `.gitmodules` and `PageLanguageApi` )
- [ ] Remove tests in `intregation/config` ( `zuul/layout.yaml` )
- [ ] Remove from `translatewiki` ( `groups/MediaWiki/mediawiki-extensions.txt` )
- [ ] Mark as read-only on Gerrit
Note: As mentioned by @Mainframe98 [[https://www.mediawiki.org/w/index.php?title=Topic:Tlq8vz7mmipvkpur&topic_showPostId=tmi455wbegf0e2ki#flow-post-tmi455wbegf0e2ki|on a Flow thread]], this should probably have to wait till official 1.29 release. No action should be taken until confirmation is given by @Mainframe98 :-)
