### Apache Airflow version

2.6.1

### What happened

When running `airflow kubernetes cleanup-pods`, the API call to delete a pod fails. A snippet of the log is below:

```
urllib3.exceptions.MaxRetryError:
HTTPConnectionPool(host='localhost', port=80): Max retries exceeded with url: /api/v1/namespaces/airflow/pods/my-task-avd79fq1 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f52f9aebfd0>: Failed to establish a new connection: [Errno 111] Connection refused'))
```

[The Kubernetes client provisioned in _delete_pod](https://github.com/apache/airflow/blob/main/airflow/cli/commands/kubernetes_command.py#L151) incorrectly has the host as `http:localhost`. On the scheduler pod if I start a Python environment I can see that the configuration differs from the `get_kube_client()` configuration:

```
>>> get_kube_client().api_client.configuration.host
'https://172.20.0.1:443'
>>> client.CoreV1Api().api_client.configuration.host
'http://localhost/'
```

On Airflow 2.5.3 these two clients have the same configuration.

It's possible I have some mistake in my configuration but I'm not sure what it could be. The above fails on 2.6.0 also.

### What you think should happen instead

Pods should clean up without error

### How to reproduce

Run the following from a Kubernetes deployment of Airflow:

```python
from airflow.kubernetes.kube_client import get_kube_client
from kubernetes import client

print(get_kube_client().api_client.configuration.host)
print(client.CoreV1Api().api_client.configuration.host)
```

Alternatively run `airflow kubernetes cleanup-pods` with pods available for cleanup
