fix(helm): explicitly define `kind` and `apiVersion` of `volumeClaimTemplate` element

[LucasVanHaaren]

Description

Hello, I made a quick fix to define explicitly all volumeClaimTemplate field. This allows to use gitops tools (like argoCD) to sync raw k8s manifests (built via helm) with cluster resources. Without these fields defined, these will be added in the cluster resource resulting in an OutOfSync with the generated manifest.

Feel free to discuss this fix in the below linked discussion.
