Fedora Copr / Mock) team is moving from IRC to Matrix

[Pavel Raiskup]

Hello maintainers!

You might have noticed that the Fedora Matrix <-> IRC bridge has been
inactive for quite some time and is unlikely to be restored soon.
Monitoring both channels has become expensive for our team.

I have personally noticed (as an IRC-only person until recently) that
Matrix has already been more active these days, especially concerning
the build system topics.  Fedora Infrastructure also seems to
transitioning (meetings, etc).

Henceforth, you can find us on the "Fedora Build System" channel at:

https://matrix.to/#/#buildsys:fedoraproject.org

We'll try to monitor the old IRC room for a while, but please note that
the Matrix channel is now the correct place for your questions.
