Here's an update on the GitHub workflows:

- I've updated the Node.js versions to 18.x and 20.x in `pull-request.yml`.
- The Node.js version in `npm-publish.yml` is now 20.x.
- I've updated `actions/checkout` to v4 in all workflows.
- Similarly, `actions/setup-node` has been updated to v4 across all workflows.
