Proposal: Harbor-Helm shoould maintain a Changelog

[Vad1mo]

When new Helm charts are released, it is difficult to see what has changed and what impacts it has on the upgrade and deployment.

One easy way to publish a Changelog can be done with artifacthub.io. Project Harbor is already listed https://artifacthub.io/packages/helm/harbor/harbor

The only thing needed is to add annotations to Chart.yaml

Artifact Hub annotations in Chart.yaml:

annotations:
  artifacthub.io/changes: |
    - Added cool feature
    - Fixed minor bug    

See full example: https://artifacthub.io/docs/topics/annotations/helm/
and code https://github.com/artifacthub/hub/blob/master/charts/artifact-hub/Chart.yaml

The result will be displayed by artifacthub like this:

It is also possible to reference directly to the Changelog from the git repo or download the markdown version containing the full change log.
