docs: Update helm-kubernetes-quickstart bundle (#7469)

The previous update of this bundle was a corrupted tarball that OPA was unable to read.

```bash
$ opa eval -b helm-kubernetes-quickstart 'data'
  {
    "errors": [
      {
        "message": "loading error: bundle helm-kubernetes-quickstart: bundle load failed on manifest decode: invalid character '\\x00' looking for beginning of value"
      }
    ]
  }
```
