Publish a docker image with tagged versions

[samos123]

I created a separate repo so I can use a public docker image here in the helm charts: https://github.com/substratusai/verba-docker

However, ideally Verba publishes an official container image and tags it with each new release of verba.

Note I'm fine with keeping my separate repo and publish container images but I might not be able to keep it up to date.

For example, I would like to see the following image published: weaviate/verba:v0.4.0
