[Vacant2333]

Please provide an in-depth description of the question you have:
Follow by https://github.com/karmada-io/karmada/blob/master/operator/README.md#helm-install
and result:

seems like values.yaml missing common

What do you think about this question?:
after
cd charts/karmada-operator
helm dependency build
it will works.

we may need add --dependency-update at the helm usage, it will be useful for first run

Environment:

• Karmada version: Latest
• Kubernetes version:
• Others:
