To update instructions to get token via helm installation

[cniackz]

Our current Operator Installation via Helm is outdated.
We have to provide new instructions on how to get the token
This is no longer working:

kubectl get secret $(kubectl get serviceaccount console-sa --namespace {{ .Release.Namespace }} -o jsonpath="{.secrets[0].name}") --namespace {{ .Release.Namespace }} -o jsonpath="{.data.token}" | base64 --decode

But this is currently working:

kubectl apply -f - <<EOF
apiVersion: v1
kind: Secret
metadata:
  name: console-sa-secret
  namespace: minio-operator
  annotations:
    kubernetes.io/service-account.name: console-sa
type: kubernetes.io/service-account-token
EOF
kubectl -n minio-operator  get secret console-sa-secret -o jsonpath="{.data.token}" | base64 --decode
