Generate Helm chart README. (#7012)

**What this PR does / why we need it**:
The Helm CI would break because the Helm chart README was not generated.
This change

* updates the README
* introduces a filter that will only run the Helm CI on changes to the
  Helm chart directory
* removes trailing whitespace
* corrects the Minio chart repository
