Expected result:

I expect to be able to provide an SSL context for the websockets to use.
I can provide one to the AsyncWebClient:

AsyncWebClient(token=BOT_TOKEN, ssl=ssl_context)

and I want to use the same context for the websocket.

Actual result:

<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)>
