wave is a Python Standard Library module

Installing the third-party ___Whole Architecture Verification___ module https://pypi.org/project/Wave is [breaking our builds](https://github.com/ArduPilot/MAVProxy/actions/workflows/windows_build.yml).

The Python Standard Library module  [`wave`](https://docs.python.org/3/library/wave.html) has an API that corresponds to:
https://github.com/ArduPilot/MAVProxy/blob/a45549f9bcb09603be1507c260de2bafe516212a/MAVProxy/modules/mavproxy_chat/chat_voice_to_text.py#L72-L78

Therefore, we should stop doing `pip install wave` and instead use the Standard Library.

The docs at https://ardupilot.org/mavproxy/docs/modules/chat.html#prerequisites must also be modified.

% `git grep wave`
