docs: wiki.lab is gone, Wiki.js in the stack took over

This file still told readers the doc sources are served side by side as a
Docusaurus site at wiki.lab. That site never went live and the name does not

pointing at something dead is worse than none, since it sends the next session
looking for a service that was retired.

 **The one write that still lands on Gitea**: the monthly TURN-rotation CronJob runs in
 the cluster (no route to git.lab) and pushes its rotation branch to Gitea. Never merge
