CI: Cancel in-progress jobs when a PR is updated (#13552)

- This should lead to faster results as jobs will be queued for shorter periods
when PRs are updated.

- Current behavior is that previously running CI jobs for an updated PR run to
completion needlessly, and cause new CI jobs to be queued.
