[Bug] can't create topic in k8s ipv6. broker

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Read release policy

- [X] I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.

### Version

k8s with ipv6
imag version:3.3.3
no client, just cli.

### Minimal reproduce step

this is my broker deploy yaml file:

### What did you expect to see?

I am a newer for pulsar, I just want to run a demo of pulsar cluster with some node.
first. I deploy my pods in k8s cluster. they are look good.
then, I want to create a topic, but I'm failed.

### What did you see instead?

in pulsar-admin cli, I got this.
``` bash
my-release-pulsar-proxy-0:/pulsar# pulsar-admin topics create public/default/test1

then I found some exception log in broker pod:

It appears that pulsar cannot use ipv6 dns server?
I confirm the dns server in log is working.
``` bash
my-release-pulsar-broker-0:/pulsar$ nslookup my-release-pulsar-broker-2.my-release-pulsar-broker.milvus.svc.cluster.local fd11:1111:1112:15:0:0:0:a
Server: fd11:1111:1112:15:0:0:0:a
Address: fd11:1111:1112:15::a#53

Name: my-release-pulsar-broker-2.my-release-pulsar-broker.milvus.svc.cluster.local
Address: 10.222.55.247
```
Can I run pulsar in ipv6 k8s cluster?

### Anything else?

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start with the provided StatefulSet, ConfigMap, and headless Service YAML, then reproduce `pulsar-admin topics create public/default/test1` while checking DNS resolution for `my-release-pulsar-broker-2.my-release-pulsar-broker.milvus.svc.cluster.local`. Done means the broker hostname resolves and topic creation completes without the HTTP 504 or connection errors shown in the broker logs.
