This is a major version bump with no functionality changes. The major version change is due to moving to node20 for the node version per the deprecation announcement for GitHub Actions (https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/). This change from node16 to node20 could cause breaking changes to other workflow actions steps (see #125) running and needing/leveraging expected functionality in node16 and thus as a safe boundary, changing the version here.
