Update website
The website seemed to be untouched for a little while. I needed to change quite a bit to make it work locally.
If thats too big to review, I can file smaller MRs, but I think all changes are needed.
- updates the dependencies to get rid of python2
- Deletes the Reddit channel from the website since I am not aware of anyone managing it
- Removes the outdated info about the sync meeting
- Add the maintainers email to contact page
