Describe the bug

We're using Sanic 21.12.2 at rasa and notice this bug whenever rasa tries to spin a sanic server,

File "/Users/zi/Work/Rasa/venv-rasa-oss-3-10-2/lib/python3.10/site-packages/sanic/mixins/startup.py", line 57, in <module>
    from sanic.server.protocols.websocket_protocol import WebSocketProtocol
  File "/Users/zi/Work/Rasa/venv-rasa-oss-3-10-2/lib/python3.10/site-packages/sanic/server/protocols/websocket_protocol.py", line 3, in <module>
    from websockets.connection import CLOSED, CLOSING, OPEN
ImportError: cannot import name 'CLOSED' from 'websockets.connection' (/Users/zi/Work/Rasa/venv-rasa-oss-3-10-2/lib/python3.10/site-packages/websockets/connection.py)

It seems like https://github.com/sanic-org/sanic/pull/2609 addresses it but these changes are not available to the branch for version 21 21.12LTS.

Code snippet

No response

Expected Behavior

I would have expected to not see any error when starting the sanic server. I get expected behaviour when using sanic version 22.12.0 and 23.3.0

How do you run Sanic?

Sanic CLI

Operating System

MacOS

Sanic Version

Sanic 21.12.2; Routing 0.7.2
