Allow json like messages for WS

[wasder]

Describe the bug When I make a request to mock file below, I get an error. Allow json like messages for WebSocket. Now I have to stringify WS json message.

To Reproduce Steps to reproduce the behavior:

1. Mock File Content ws_mocks/message.mock

   {
   "self": {
       "status": "OK",
       "result": {
           "service": {
               "abc": "123"
           }
       }
   }
   }

2. Error Stack Trace

   
   throw new ERR_INVALID_ARG_TYPE(
   ^

TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be of type string or an instance of Buffer, ArrayBuffer, or Array or an Array-like Object. Received an instance of Object at new NodeError (node:internal/errors:371:5) at Function.from (node:buffer:322:9) at toBuffer (/usr/local/lib/node_modules/camouflage-server/node_modules/ws/lib/buffer-util.js:97:18) at Sender.send (/usr/local/lib/node_modules/camouflage-server/node_modules/ws/lib/sender.js:265:17) at WebSocket.send (/usr/local/lib/node_modules/camouflage-server/node_modules/ws/lib/websocket.js:421:18) at Timeout._onTimeout (/usr/local/lib/node_modules/camouflage-server/dist/parser/WebsocketParser.js:61:28) at listOnTimeout (node:internal/timers:557:17) at processTimers (node:internal/timers:500:7) { code: 'ERR_INVALID_ARG_TYPE' }

**Expected behavior**
Expects above mock file to work as is.
