[k8s-runner.yaml](https://github.com/grafana/quickpizza/blob/main/k6/k8s-runner.yaml) uses `configMap` to [run a distributed k6 test](https://k6.io/docs/testing-guides/running-distributed-tests/). It would be good to add another example using persistent volumes. Also copy the example [here](https://github.com/grafana/k6-operator/blob/main/config/samples/k6_v1alpha1_k6_with_volumeClaim.yaml).
