Add proper version tagging for GitHub releases

[CarrotManMatt]

• Make build image run on tagged commit rather than push to main
• Workflow for when pyproject.toml tag does not match tagged commit
• Remove commit tag when above workflow fails
• Make first major stable release

See https://github.com/CarrotManMatt/typed_classproperties for a good example of version tagging. This would need to be adapted to build the Docker image rather than publish to PyPI

Pull request branches now have a development container image built for every change. Merged in #271
