Inconsistent timeout of WSClient.update

[t-yrka]

What happened (please include outputs or screenshots):

https://github.com/kubernetes-client/python/blob/master/kubernetes/base/stream/ws_client.py#L182-L189
The timeout behavior of the update method is inconsistent.
Function select.select interprets timeout as floating-point seconds where the polling object (poll method) uses milliseconds.

What you expected to happen:

The timeout unit is the same in all cases.

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

Exec update with select and poll.

Anything else we need to know?:

Environment:

• Kubernetes version (kubectl version):
• OS (e.g., MacOS 10.13.6):
• Python version (python --version) 3.10.8
• Python client version (pip list | grep kubernetes) 25.3.0
