Bug Description

If you use the GitHub Action workflow example as-is, every sync of commits to a PR results in a report from OCR, whether or not that's helpful or spammy.

Steps to Reproduce

Install the example GitHub workflow as-is, then open a PR and make a quick succession of commits to the branch, eg via the GitHub web interface. You'll notice have many OCR reviews in flight in parallel, and when they complete they'll all pile up repetitive posts on the PR.

Expected Behavior

If there is any OCR action in progress, it should be canceled before it has a change to complete and post on the PR. The review should include everything from the root of the branch, not just the commits that trigger the review.

Logs / Error Output

Additional Context

You can implement the desired behavior by putting this above your triggers:

concurrency:
  group: ${{ github.workflow }}-${{ github.event.pull_request.number || github.ref }}
  cancel-in-progress: true
