Release Helm Chart workflow is not automatically triggered

[didierofrivia]

Describe the bug
The GH Action Release Helm Charts is not triggering when a release is published.

To Reproduce
The action should be triggered automatically when a release is published. However, this is not happening.

Expected behavior
Once a release is published, the Release Helm Charts workflow should be triggered.

Additional context
The issue might be related to the fact that now the releases are automated, we might want to hook the event to an additional trigger.
