Operator docs may require enhancement

[Vacant2333]

What would you like to be added:
Operator docs may require enhancement
https://github.com/karmada-io/karmada/blob/master/operator/README.md

Why is this needed:
for example:
we can add the the usage to get the karmada-apiserver's kubeconfig
kubectl get secret -n {namespace} karmada-demo-admin-config -o jsonpath='{.data.config}' | base64 --decode > kubeconfig.yaml

[calvin0327]

@Vacant2333 Thanks pointing this, there is a better way to get the karmada config:

kubectl get secret -n <KARMADA_NAMESPACE> $(kubectl get karmada -n <KARMADA_NAMESPACE> <KARMADA_NAME> -ojsonpath='{.status.secretRef.name}') -ojsonpath='{.data.config}' | base64 -d > config
