Additional automation in the release actions workflow

[tbenthompson]

remaining tasks to automate in the publish CI workflow:

• publish to test pypi first
• then, check the published package
• then, republish to real pypi
• then, run the automatic release action.

no time to continue this now, but I'll get back to this the next time I need to push a release.

There's also a bump version workflow that I could manually trigger to start the process: https://github.com/MylesBorins/node-osc/blob/main/.github/workflows/bump-version.yml
