Steps to reproduce:

1. using chart[ helm 1.3.5 of version 6.4|https://cdn.zabbix.com/zabbix/integrations/kubernetes-helm/6.4/zabbix-helm-chrt-1.3.5.tgz]
2. setup zabbix-proxy with{{ zabbixProxy.persistentVoluime.enabled: true}}
3. keep zabbixProxy.existingClaim empty as defined by default.

Result:
no PersistentVolumeClaim are created and deployment is setup with the volume attachment. Result pod doesn't start.

0/6 nodes are available: persistentvolumeclaim "zabbix-chart-zabbix-helm-chrt-proxy" not found.

Expected:
As indicated in helm documentation zabbixProxy.persistentVoluime.enabled should create the PVC zabbixProxy.existingClaim is empty .

By looking at template in chart helm there is no kind PersistentVolumeClaim.
