[workflows] Github workflows for synchronize a release and upload chart

* When a release is published, the `release-helm-chart` workflow will
  package the chart and upload it to the release page. Then sync with
the kuadrant repo. For this is necessary to build the manifests and
chart before the release. Running `make helm-build` with the require envs
to be released
* When a release is deleted, it will sync with the kuadrant repo
