repair "docker push" in docker-publish make target

* the commit 393daca85 broke the docker-publish make target by removing
  the indentation for the "docker push ..." command
* readd the correct indentation to allow "docker publish" make target to
  upload new image tags
* this change will only fix the behaviour for future releases, all tags
  added between v3.4.0 (last published tag before commit 393daca85) and
  now have not been published
* increase VERSION to v3.4.7 to trigger automatic tagging and jenkins
  docker-build/publish jobs to upload newest release
