As promised a reworked GitHub Action.

Required Secrets:

• DOCKERHUB_IMAGENAME, e.g gilleslamiral/imapsync
• DOCKERHUB_TOKEN, i.e a Docker Hub Personal Access Token to be able to push images
• DOCKERHUB_USERNAME, e.g. gilleslamiral

The action runs on every push to master, but only pushes if a new matching tag was created - the tag ist then used for the Docker tag as well.

If you somewhen plan have the latest imapsync version on GitHub the Dockerfile can be optimized further, to get rid of the wget which is currently used.

Thanks for this request.
The problem is that I don't want to trigger a Docker image creation and publishing without testing it before.

Full understandable, I'm used to this as well. Therefore, the proposed Action only triggers when a release is tagged in the Git repository.
