Documentation is outdated in HACKING/GettingStarted.md
While handling #33741 (closed), I saw in the mentioned file that the documentation states :
8. Submitting your patch We review patches through tickets on our bugtracker at [trac](https://trac.torproject.org). You can either upload your patches there, or put them at a public git repository somewhere we can fetch them (like gitlab, github or bitbucket) and then paste a link on the appropriate trac ticket.
This is not true anymore as we use Gitlab. I can modify this to give the gitlab link and add a sentence saying that if users want to use gitlab, they need to ask for an account.
I will then make two separated MR for #33741 (closed) and this issue.
