[Bug] Pulsar broker doesn't use functions_worker.yml file

### Search before asking

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

### Version

Pulsar version 2.9.1
Debian 11

### Minimal reproduce step

I have a cluster of 6 machines. 3 servers run broker and bookkeeper, 3 run zookeeper. Firstly, I configured functions_worker.yml like this on 3 separate broker servers. first one looks like this. config is similar in all three machines.

workerId: "test"
workerHostname: "vtst-eims-pbb1.corp.rst.lt"
workerPort: 6750
workerPortTls: 6751
configurationMetadataStoreUrl: zk:172.28.80.233:2181,172.28.80.234:2181,172.28.80.235:2181

Then set this parameter in broker.conf and restarted the broker.
functionsWorkerEnabled=true

### What did you expect to see?

I expected the broker to call the correct zookeeper cluster and display correct values.

### What did you see instead?

But for some reason my worker id is not changing,
{"workerId":"c-pulsartst-fw-vtst-eims-pbb1.corp.rst.lt-8080","workerHostname":"vtst-eims-pbb1.corp.rst.lt","port":8080}

and broker keeps connecting to local zookeeper, which this server doesn't have. My config file has no mention of localhost connection, i have no idea why it keeps doing that
