Check tag consistency as a requirement to publishing

[javiermtorres]

What's changing

A semver tag starting with 'v' will trigger publishing to PyPI, but only if the version in the pyproject.toml files from SDK and schemas match with the git tag.

How to test it

Make a commit and git-tag it with a semver tag (e.g. v0.0.0) that does not match with the contents of the pyproject.toml files either the lumigator/python/mzai/sdk or lumigator/python/mzai/schemas directories. The publishing step should trigger but fail.

Additional notes for reviewers

Fixes #363

I already...

• added some tests for any new functionality
• updated the documentation
• checked if a (backend) DB migration step was required and included it if required
  • No DB migration step required
