Subject: [PATCH] [webpack-dev-server] Add httpProxyMiddleware.Filter support
 to context property of ProxyConfigArrayItem

webpack-dev-server [proxy documentation](https://webpack.js.org/configuration/dev-server/#devserverproxy) gives an example of using Filter function for context property and in reality dev-server supports it. However, it was missing on `@types/webpack-dev-server`.
