Update workflow to publish docker & helms [master]

Update workflow to publish docker & helm charts

• workflow should expect & use already released & published lighty-core artifacts in maven-central. These release artifacts is used & included during building docker image.
• also the workflow is updated with another parameter to specify if the image to publish is also latest docker image, so latest tag will be applied for the image and pushed to docker hub.
• merged multiple version parameters into single value, minimizing cases when the user forget to input helm-charts version. The version used for docker tag and helm charts is same for most use-cases, if not for every use-case.

Maybe we want to change the description of helm chart of lighty-rnc from the default one https://github.com/PANTHEONtech/helm-charts/blob/main/index.yaml#L7 ?
That can be changed in Chart.yaml.
Otherwise the workflow looks fine, but one question:
If you now pushed for example version 14.0.0 without latest tag, would the latest tag stay on the current version (13.2.1) ?
