Cancel Actions

Our actions can run pretty long. We can use this action to cancel them when another commit is pushed on the same branch https://github.com/styfle/cancel-workflow-action

Review the repository's GitHub Actions workflow files and the linked cancel-workflow-action documentation. Confirm how workflows are currently triggered, then configure cancellation for older runs when a new commit reaches the same branch. Done means a newer commit cancels the earlier in-progress run.
