storageDataPath not working as expected for VMSingle

[nebula-it]

storageDataPath docs mention that defining it would disables spec.storage option, but it does not seem to.

e.g Deploying this spec:

---
# Source: vm-stack/charts/vm-stack/templates/victoria-metrics-operator/vmsingle/vmsingle.yml
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMSingle
metadata:
  name: release-name-vm-stack
  namespace: victoria-metrics
  labels: 
    app.kubernetes.io/component: vmsingle
    app.kubernetes.io/instance: release-name
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: vm-stack
    app.kubernetes.io/version: v1.150.0
    helm.sh/chart: vm-stack-0.91.2

    resources:
      requests:
        storage: 20Gi
  storageDataPath: /vmsingle-data
  volumeMounts:
  - mountPath: /vmsingle-data
    name: vm-single
    subPath: long-term
  volumes:
  - name: vm-single
    persistentVolumeClaim:
      claimName: vm-single

results in following error (kubectl describe vmsingles.operator.victoriametrics.com release-name-vm-stack) :
Warning ReconciliationError <unknown> victoria-metrics-operator failed create or update vmsingle: cannot generate prev deploy spec: unexpected volume="vm-single" mounted to path="/vmsingle-data", which is reserved for volume="data", path="/vmsingle-data"

Linked issue on helm chart side VictoriaMetrics/helm-charts#3195, as that is preventing us to not define storage: key at all.

Expected behavior

As per the docs, with storageDataPath: /vmsingle-data set, the storage: should have been ignored completely. Plus the value of storageDataPath should also be added to extraArgs
