New content has landed in the 2.5 branch, so let's merge the changes into 2.6

CI passes but for some reason precommit can't reach https://github.com/mixxxdj/mixxx/issues/

Run appstreamcli validate res/linux/org.mixxx.Mixxx.metainfo.xml
  appstreamcli validate res/linux/org.mixxx.Mixxx.metainfo.xml
  shell: sh -e {0}
W: org.mixxx.Mixxx:89: url-not-reachable
     https://github.com/mixxxdj/mixxx/issues/ - Unexpected status code: 503

Besides that, is there anything else we need to pay attention to when merging CI updates?
(not familiar with that, do we freeze some runner/hook versions or something?)

In the past I did a short smoke test at least when merging manual. I think we should still do it in case of bigger functional changes. In this case we have no functional change to test.

This CI failure is Code 503 "Service Unavailable"
Probably only a temporary issue. I try to restart

Yeah, I already restarted that, still 503
And yes, that's not blocking.
