Improve formatting for past Hackweek documentations
While working on #13 (closed), Hackweek got a website: https://tpo.pages.torproject.net/community/hackweek/
Now it's way easier to browse and search for past projects, but this also exposes the need to fix formatting at some pages.
This ticket is about fixing the formatting for the existing docs.
This is not a regular Hackweek proposal. Instead, it's is an actual task to improve it's documentation.
