goal - perserve github action workers
normal behavior when pushing to a pr branch that already has a workflow/ci running is to queue an additional run of the
workflow/ci and all jobs for each push. this can result in a single pr exhausting all available workers, and a user
waiting on ci to finish for a previous commit in the pr, when the general preference is to get a complete run of just the
latest pr. using https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#concurrency
we can cancel the in progress runs, and free up workers to run workflow/ci for the latest push sha.
