Note

Low Risk
Low risk dependency bump in the GitHub Actions workflow; main impact is potential CI behavior change if the new docker/build-push-action digest has breaking changes.

Overview
Updates the Docker publish GitHub Actions workflow to use a newer pinned digest of docker/build-push-action for the build-and-push step.
