`sec-websocket-protocol` header defaults to `v4.channel.k8s.io` causing HTTP 400

**What happened (please include outputs or screenshots)**:
We are running our tool Gefyra to fetch environment variables from a running pod/container via a usual `stream` over `connect_get_namespaced_pod_exec`:

https://github.com/gefyrahq/gefyra/blob/42879723d8a9265ed77faab3b23c47763950a461/client/gefyra/cluster/utils.py#L26-L36

In one of our environments, I am receiving an HTTP 400 for the WebSocket upgrade call. However, the equivalent `kubectl exec ...` executes properly.

From somewhere in the stack trace: `websocket._exceptions.WebSocketBadStatusException: Handshake status 400 Bad Request - ...`

So I looked for the differences between `kubectl` (v1.31.1) and the Python package (31.0.0). I was able to trace the problem back to the `sec-websocket-protocol` header, which defaults to `v4.channel.k8s.io`

https://github.com/kubernetes-client/python/blob/230925f33859818a65cf22fa57196f162e0cecfd/kubernetes/base/stream/ws_client.py#L468-L472

The value of the `sec-websocket-version` is set to `13` with both `kubectl` and `kubernetes-python`.
Unfortunately, I couldn't find many sources on this, except https://kubernetes.io/blog/2024/08/20/websockets-transition/.

After patching the content of `kubernetes/base/stream/ws_client.py` in my site-packages to `v5.channel.k8s.io` it started to work again.
Now I am looking for a solution to pass this header from our code to get rid of the monkeypatch, but without constructing the `WSClient` myself.

Is this some special setting in our environment (I mean to prevent `v4.channel.k8s.io` from working) or does that apply to all K8s clusters starting from 1.30.x?

**What you expected to happen**:
The `stream` over `connect_get_namespaced_pod_exec` to work with `sec-websocket-protocol` set to `v5.channel.k8s.io`.

**How to reproduce it (as minimally and precisely as possible)**:

**Anything else we need to know?**:

**Environment**:
- Kubernetes version (`kubectl version`):

```
Client Version: v1.31.1
Kustomize Version: v5.4.2
Server Version: v1.30.1
```

- OS (e.g., MacOS 10.13.6):

```
Linux/Container
```

- Python version (`python --version`)

```
Python 3.9.20
```

- Python client version (`pip list | grep kubernetes`)

```
kubernetes 31.0.0
```

Thank you for your good work.
