Project's missing RELEASE.md and CHANGELOG.md equivalents

[consideRatio]

I wanted to link to a changelog for this project but didn't find one, and then I saw also that the latest release was made with an error message in the commit message title which made me notice there wasn't a RELEASE.md procedure or automation to push to PyPI etc.

I suggest adopting:

• a CHANGELOG.md file
• a release.yaml github workflow, using pypi's trusted credentials as mentioned in the workflow
• a tbump config
• a RELEASE.md file, describing how to make a release using tbump in combination with the github workflow and github-activity itself to update the projects own changelog

There is a changelog, and there is a contributing.md with release instructions.

I think use of tbump simplifies things over using the GitHub UI to publish a release and tags - but this is mostly addressed so closing
