Description

See #39450 or #39325 as examples

We likely use code that is incompatible with new versions. However we should be able to take in bug fixes, so we should fix our code to work.

Darwin and linux seems to fail websocket connections on 9002 for some reason when new websockets library is used:

...
ERROR   09:51:43.354 - PAIR ERR  :     raise Exception(f'Connecting to {url} failed.')
479
ERROR   09:51:43.354 - PAIR ERR  : Exception: Connecting to ws://localhost:9002 failed.
480
ERROR   ================ CAPTURED LOG END ====================
481
ERROR   DL_LockUnlock                  - FAILED in 51.72 seconds

Cannot see any obvious reasons in log, so we may want to improve logging and debug.

Research direction
Investigate the failure of libwebsockets dependabot updates by examining examples #39450 and #39325. Focus on the websocket connection failure on port 9002 on Darwin and Linux. Improve logging in the websocket handling code within the connectedhomeip repository to identify the root cause. The fix likely involves updating C++ code to be compatible with the newer libwebsockets API.
