[Documentation] Use WebGPUExecutionProvider from python (or other non-web platform)

[xenova]

Describe the documentation issue

I've tried searching the documentation for instructions on how to use the WebGPUExecutionProvider from python, but no results seem to show up.

>>> import onnxruntime
>>> onnxruntime.version
'1.23.1'
>>> onnxruntime.get_available_providers()
['CoreMLExecutionProvider', 'AzureExecutionProvider', 'CPUExecutionProvider']

OS: macOS 15.6

It would be very useful to show how to use the WebGPU EP outside of web-specific platforms. Is it necessary to install onnxruntime-gpu too?
