Authentication check doesn't work properly for websocket stream connections which require authentication

[lz-44]

When subscribing to a stream that requires authentication (e.g. wallet stream) like this:

WebsocketStreamClient wsClient = this.wsFactory.newWebsocketClient(this::handleWalletEvent);
wsClient.getPrivateChannelStream(List.of("wallet"), "/v5/private");

we are getting the following error:
[OkHttp https://stream-testnet.bybit.com/...] ERROR c.b.a.c.w.i.WebsocketStreamClientImpl - Authentication failed.

After debugging a bit I found that the error happens with the messages of auth type, like this:

{
  "req_id": "1e979e9f-c8ea-44f5-a631-79fc82af7f41",
  "success": true,
  **"ret_msg": ""**,
  "op": "auth",
  "conn_id": "cqg7829qo29sr7bfifu0-cuck"
}

Despite the authentication in fact was successful, the check had failed:
isAuthenticated = msg.contains(""retCode":0"); (WebsocketStreamClientImpl:265)

and that's why we see the error message.

I have been using this API for a while and don't remember these errors. Probably the response from Bybit has been slightly changed. Maybe we should rely on "success" field?
