`websockets.legacy` now deprecated with websockets `v14.0`

[devennavani]

websockets v14.0 was released yesterday which deprecates use of websockets.legacy:

https://github.com/python-websockets/websockets/blob/f0d20aafab027e9b99460b193dcb709872b219a5/src/websockets/legacy/__init__.py#L7

This breaks sanic-testing as it relies on websockets.legacy via from websockets.legacy.client import connect in websocket.py

The websockets upgrade guide suggests replacing from websockets.legacy.client import connect with from websockets.asyncio.client import connect
