operator: dial tcp: lookup karmada-webhook.karmada-system.svc on x.x.x.x: no such host

[zhzhuang-zju]

What happened: when deploying karmada instance by operator，karmada-apiserver will report dial tcp: lookup karmada-webhook.karmada-system.svc on x.x.x.x: no such host error if the namespace of karmada instance is not karmada-system.

What you expected to happen:

How to reproduce it (as minimally and precisely as possible):

• Follow Tutorial https://github.com/karmada-io/karmada/blob/master/operator/README.md and deploy karmada instance in namespace test
• print the log of karmada-apiserver

Anything else we need to know?:

Environment:

• Karmada version: v1.9.0
• kubectl-karmada or karmadactl version (the result of kubectl-karmada version or karmadactl version):
• Others:

cc @calvin0327 to confirm I remember it's the basic use case that enables installation in customized namespace.
