update statefulset to inlcude verbose PVC reference

[ritzk]

Description

The issue is that the verbose reference is added once ArgoCD applies the chart to cluster. This results in ArgoCD thinking there is a diff, when there is none. This can be solved by adding a patch which adds the verbose reference.
