Reason
Extension was imported to gerrit on Oct 6 - https://gerrit.wikimedia.org/r/#/q/project:mediawiki/extensions/TagContent
mediawiki.org page gets archived template on Oct 4 - https://www.mediawiki.org/w/index.php?title=Extension:TagContent&oldid=3441178

I am not sure if this should be archived or reactivated.
Please leave a comment if it should exists on gerrit or not. Thanks.
