Display Helm metadata in the UI
Context
In #18997 (closed), we delivered an MVC of Helm chart support in the GitLab Package Registry. You can publish and install packaged helm charts and authenticate using a job, deploy, or personal access token. You can view the package in the Package Registry UI.
Problem to solve
The problem is that the user interface doesn't yet display the key metadata associated with a Helm chart. Developers need the ability to see branch/commit data when a package is published using GitLab CI. In addition they need to be able to see the metadata associated with the package.
Proposal
Update the Package Registry to include branch and commit data for Helm charts that have been published using GitLab CI/CD. Display the below metadata for helm charts in the UI:
apiVersion: The chart API version (required)
