Subject: [PATCH] ci: cancel previous jobs on ref update

Let's save the environment (and reduce the number of jobs in GH Actions
queues) by cancelling old jobs on a ref update (force push).

See: https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions#concurrency
(cherry picked from commit 3884837610168e6fb69fc2d5709f6c017a30beb9)
