Do not udpate forbidden fields for statefulset

[dolohow]

Every time I upgrade this helm chart I got this error

Error: UPGRADE FAILED: cannot patch "vaultwarden" with kind StatefulSet: StatefulSet.apps "vaultwarden" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'ordinals', 'template', 'updateStrategy', 'persistentVolumeClaimRetentionPolicy' and 'minReadySeconds' are forbidden

Lets not put all the labels from helper, because they contain also chart version which changes on every upgrade

    volumeClaimTemplates:                                                                                            
      - metadata:                                         
          name: vaultwarden-data                          
          labels:                                         
-             helm.sh/chart: vaultwarden-0.20.0
+             helm.sh/chart: vaultwarden-0.22.1           
              app.kubernetes.io/name: vaultwarden         
              app.kubernetes.io/instance: vaultwarden
-             app.kubernetes.io/version: "1.30.1"      
+             app.kubernetes.io/version: "1.30.3"
              app.kubernetes.io/managed-by: Helm

I'm just another contributor on this repo like yourself, but I believe that @guerzon has the default behavior set to Squash and merge, as was my experience on the PR that I just raised a couple days ago.
