LocalWebservice exposing wrong port

When I try to deploy a dummy with LocalWebservice it exposes the wrong port making failing the deploy which causes it to hang and be unavalible. I run the code:

```python
from azureml.core import Workspace, Environment
from azureml.core.model import Model
from azureml.core.webservice import LocalWebservice
from azureml.core.model import InferenceConfig

ws = Workspace(
subscription_id=subscription_id,
resource_group=resource_group,
workspace_name=workspace_name,
auth=auth,
)
deployment_config = LocalWebservice.deploy_configuration(6584)
inference_config = InferenceConfig(environment=env,entry_script="./echo_score.py")
service = Model.deploy(
ws,
"myservice",
[],
inference_config,
deployment_config,
overwrite=True,
)

service.wait_for_deployment(show_output=True)
```

```python
%% echo_score.py
import json

def init():
print("This is init")

def run(data):
test = json.loads(data)
print(f"received data {test}")
return f"test is {test}"
```
It yields the following output where it hang at the last step:

When i run `docker ps` i get that port 6584 maps to 5001
```

```
but if I get the logs with `docker logs 5d61a0df3ee4 ` Iget the following showing that it should be port 31311 that should be exposed:

If I `exec` into the container an curl on ` 127.0.0.1:31311/` I do get a prober health check.

I'm using `azureml-core==1.33.0` on Windows in `python=3.8.8`
