Failing DockerVersion test

[jNullj]

:clock11: When did the problem start?

Here at CI

:camera: Live badge

:wrench: Is the live badge working?

Working, but we test for semver while values are tags and commonly don't use semver.

:bulb: Possible solution I noticed python seems to follow only semver tags. I think its better to change to it rather then try to write constraints for image tags that don't follow a specific ruleset.
