Feature request: Please add webSocket support in network inspector

Hi Flutter DevTools team,

While using DevTools to debug my Flutter applications, I've found that it currently lacks the ability to inspect WebSocket connections. This has made it difficult for me to debug Flutter apps that rely on WebSocket.

Would you consider adding this feature in a future release? With a WebSocket connection inspection feature, we would be able to better understand the status of WebSocket connections in our apps and the data being transmitted, which would be very helpful for debugging these types of Flutter applications.

I hope you can implement this feature soon, thank you!

该 issue 未指定文件、测试或入口点。首先定位 DevTools 中的网络检查器，并确定应如何表示 WebSocket 连接状态和传输的数据；当所请求的 WebSocket 检查功能已实现并经过验证时，即视为完成。
