### Apache Airflow version

2.6.1

### What happened

I am pulling a variable from Google Secret Manager and I'm using it as an argument in a KubernetesPodOperator task. I've also tried it with the KubernetesPodOperatorAsync operator and I'm getting the same behaviour. 

The variable value is not masked on Rendered Template page. If I use the exact same variable in a different operator, like the HttpSensorAsync, it is properly masked. That is quite critical and I can't deploy the DAG to production.   

### What you think should happen instead

The variable in the KubernetesPodOperator should be masked and only '***' should be shown in the Rendered Template page

### How to reproduce

Here's the example of code where I use the exact same variable in two different Operators. It's in the arguments of the Kubernetes Operator and then used in a different operator next.  

```
    my_changeset = KubernetesPodOperator(
        task_id='my_load',
        namespace=kubernetes_namespace,
        service_account_name=service_account_name,
        image='my-feed:latest',
        name='changeset_load',
        in_cluster=in_cluster,
        cluster_context='docker-desktop',  # is ignored when in_cluster is set to True
        is_delete_operator_pod=True,
        get_logs=True,
        image_pull_policy=image_pull_policy,
        arguments=[
            '-k{{ var.json.faros_api_key.faros_api_key }}',
        ],
        container_resources=k8s.V1ResourceRequirements(requests=requests, limits=limits),
        volumes=volumes,
        volume_mounts=volume_mounts,
        log_events_on_failure=True,
        startup_timeout_seconds=60 * 5,
    )

    test_var = HttpSensorAsync(
        task_id=f'wait_for_my_file',
        http_conn_id='my_paymentreports_http',
        endpoint='{{ var.json.my_paymentreports_http.client_id }}/report',
        headers={'user-agent': 'King'},
        request_params={
            'access_token': '{{ var.json.faros_api_key.faros_api_key }}',
        },
        response_check=lambda response: True if response.status_code == 200 else False,
        extra_options={'check_response': False},
        timeout=60 * 60 * 8,
    )
```

The same {{ var.json.faros_api_key.faros_api_key }} is used in both operators, but only masked in the  HttpSensorAsync operator.
