Issue: https://github.com/grafana/deployment_tools/issues/36289
Based on the new image: https://github.com/grafana/deployment_tools/tree/master/docker/package-publish
This is a new step meant to replace the store-packages command. It will greatly improve publishing performace and it publishes to a common repository shared with all Grafana products
