ods-deploy-helm release-name is component not the chart-name

Currently the documentation at https://github.com/opendevstack/ods-pipeline/blob/master/docs/tasks/ods-deploy-helm.adoc states: "The Helm release name. If empty, the release name is simply the name of the chart."

However it actually defaults to the component name see https://github.com/opendevstack/ods-pipeline/blob/01a67e7a6a1dcb98045e73bbefc939cb854084c9/cmd/deploy-helm/steps.go#L86-L90

To me what is documented makes more sense but it should be consistent.
