Fix and document process to update the web wikis
The web wikis are supposedly synchronised, but since a while they are out of sync.
AFAIK, the main wiki is at https://gitlab.torproject.org/tpo/web/wiki/ and it should appear under wiki in https://gitlab.torproject.org/tpo/web/community/-/wikis/home , https://gitlab.torproject.org/tpo/web/support/wikis/home, https://gitlab.torproject.org/tpo/web/manual/-/wikis/home etc.
But there is a big 'edit' button on each of the wikis, and changes have been made to the different versions
Unify the updates on the main wiki
Remove the edit buttons or make sure they go to the proper wiki to edit
Document the best way to edit and check that it works.
