adding webpack-dev-server configuration for public url

We trying to test by placing public Client URL so that we would able to get the development page on a public URL instead of default localhost.
Based on the following configuration:

https://github.com/webpack/webpack-dev-server/blob/3c1ff11c1ce4ec8d990ca0b9dc1460cd906f986f/examples/cli/public-protocol/webpack.config.js#L12

I have tried by entering these value here

  devServer: {
    host: '0.0.0.0',
    public: 'https://testwebsite.xxxxx.com',
    disableHostCheck: true
  }

spinjs/src/executor.ts

Line 464 in ba8a348

...config.devServer,

We able to open the url, but we see the socket still trying to connect localhost.

Even tried setting the browser url here, but no luck.

spinjs/src/plugins/WebpackPlugin.ts

target: proxyUrl,
