chore: cancel running CI jobs if a new commit is pushed #534
Description
We could apply something like this to cancel long running jobs like miri tests if we push multiple commits in succession:

concurrency:
# github.workflow: name of the workflow
# github.event.pull_request.number || github.ref: pull request number or branch name if not a pull request
group: ${{ github.workflow }}-${{ github.event.pull_request.number || github.ref }}
# Cancel in-progress runs when a new workflow with the same group name is triggered
cancel-in-progress: true
