Subject: [PATCH] Cancel outdated CI runs

Adds a concurrency group to the CI workflows, so a new push to a pull
request or branch cancels the runs still going for the previous commit
instead of letting them finish for nothing. It uses the same group the
app repositories already have (github.workflow plus head_ref || ref),
so pull requests and branches never cancel each other. Release, notify
and docs deploy workflows are left as they are.
