Docker image versioning strategy #362

Is your proposal related to a problem?

Docker image latest also includes main builds.
And no tag including all major (or minor) version images exist.

Describe the solution you'd like

Only publish release images to the latest tag (only main).
And also push all same major and minor versions to a separate tag (e.g. v4 v4.0 v4.0.9 latest).

Here a Github action for doing the job: https://github.com/docker/metadata-action
