Bugtracker Migration to GitLab Completed

Things did go smooth and we migrated all issues from flyspray to GitLab! 🥳

This implies the following changes:

• Bugs for packages are now opened on the repo hosting the corresponding packaging sources, “Add a new Bug” on the package page will automatically direct you to the correct package.
• A list of all issues can be found here. To filter for issues assigned to a specific package maintainer, use the filter input box. A link containing the filter can be bookmarked for convenience.
• Merge Requests for packaging repos have been enabled
• bugs.archlinux.org is readonly and will be replaced by a static clone of the site soon
• Navbars on our major webpages have been updated to include a link to GitLab instead of flyspray
• the flyspray-migration test group (referenced in previous mails in this thread) has been deleted
• Arch Linux Package Maintainers that also want to be assigned to unconfirmed bug of their packages have to react with “🔍” to this issue
