Updated readme

[daladim]

A few updates because the readme does not look up-to-date anymore.

Also, I'm not totally sure about my second commit. I first configured a random secret, and maubot would reply HTTP 401 (Unauthorized) to /_matrix/maubot/plugin/gitlab/webhooks.

After I understood where to get the secret, Maubot now replies a 403 (Forbidden). I think that's slightly better, but this still does not work. Am I doing something wrong? (I'm still trying to get the Gitlab bot up and running, but that still isn't working for me).

By the way, I am trying the manual setup of webhooks because the automated !gitlab webhook add https://gitlab.corp.com group/project failed with the following error. Should I open a new issue?

Hook executed successfully but returned HTTP 403 403: Forbidden The bot is not in the room. Please invite @gitlab_bot:hlab.ems.host to the room.`

I changed the room to an ID where the bot actually was, and it now works

I've added a line in the Readme so that others will not have the same trouble :-)
