Link to GitHub issue tracker is broken on Nextcloud support page

[stefan-it]

Link to the GitHub issue tracker is broken on the NextCloud support page:

Steps to reproduce

1. Go to https://nextcloud.com/support/
2. Click on the bug trackers link

Expected behaviour

Redirect should point to GitHub issue page

Actual behaviour

Link is broken - it will point to https://github.com/nextcloud/server/blob/master/.github/CONTRIBUTING.md and this leads to an 404 error.

Thank you for your report 😁 But this is the repo for the server, and not the website (nextcloud.com). You will find it's issue tracker over here: https://github.com/nextcloud/nextcloud.com

I'll take care of fixing it ✊
