Creating a community wiki hub/repository

Hi,

I have a proposal for improving the current wiki chaos:

I think we are missing a lot by not having a central and public wiki like the one in Trac. There were very many non-technical wiki pages about various meetings, opinions, projects built by the community, etc. that helped to develop and engage the Tor community. I was even browsing the Trac wikis in my free time to find interesting pages, and I was learning a lot.

Now, wiki pages are scattered across different repositories, and one cannot easily browse these pages. I'm not proposing to put all wiki pages back into a single repository on GitLab, but creating a dedicated official "community repository/project" for hosting wiki pages created by the community. Ideally, this dedicated repository should be editable by anyone with a GitLab account (like the Trac's public wiki pages). For example, if I hate Cloudflare blocking Tor and let people know about this, I should be able to create a wiki page about my arguments in the dedicated repository. Yes, I could do the same thing in my personal repository, but you know, who cares about my personal repositories and reads wiki pages in them. So, this repo would serve as a "community wiki hub" and provide some sort of visibility & organization.

The dedicated repository can also be useful for indexing wiki pages in other repositories. People can create wiki pages in the dedicated repository that point people to other wiki pages in other repos. Next time when someone asks "where is the X wiki page on GitLab?", the dedicated repo can be the first place to check to find the right pointer.

Finally, wiki.torproject.org would point to this dedicated repo. Currently, it points to the Trac wiki.
