fix[kubernetes-operator]: Wrong nindent for array values

[alice-dops]

Before this fix, I couldn't add volumes and volumesMount because of bad nindent
with actual values, volumes and ninent get to one more tab than other volumes and volumeMounts

Before fix

Error

 Upgrade failed: YAML parse error on kubernetes-operator/templates/deployment.yaml: error converting YAML to JSON: yaml: line 91: did not find expected key

Values

operator:
  volumeMounts:
  - mountPath: "path"
    name:  "vol"
    readOnly: true
    subPath: "subpath"

  volumes:
  - name: "vol"
    configMap:
      defaultMode: 420
      name: "conf-name"
