Upgrade http-proxy-middleware due Websocket Issue in 3.x branch

[Delagen]

Webpack: 3.11.1

// proxy.json
{
 "/ws/": {
    "target": "wss://some-server.ru",
    "changeOrigin": true,
    "logLevel": "debug",
    "ws": true
  }
}

Expected Behavior

No errors

Actual Behavior

Any WS connection to server during work cause
Error: read ECONNRESET
at TCP.onStreamRead (node:internal/stream_base_commons:213:20)
with crash

For Bugs; How can we reproduce the behavior?

For Features; What is the motivation and/or use-case for the feature?

Update version of middleware or make it less precise

Thank you for creating this issue. However, issues need to follow one of our templates so that we can clearly understand your particular circumstances.

Do not ignore how we can reproduce it, Error: read ECONNRESET means ws can't connect

[Delagen]

Yes, but it crash entire dev-server

[alexander-akait]

@Delagen Sorry using your information in the issue template I can't help you, I think nobody can help

[Delagen]

Why you simply cannot upgrade package http-proxy-middleware in webpack-dev-server 3.x version?

Because it will be breaking change, it updated for v4 (beta)
