fix(stark-build): remove support for obsolete webpack-monitor

BREAKING CHANGE:
  Due to Angular upgrade, webpack-monitor stopped working. Since the package was no longer maintained (4 years),
  we decided to remove the support from `stark-build`.

  The following scripts should be removed from "package.json" file:

  ```json
  {
    "scripts": {
      "build:dev:monitor": "npx mkdirp reports && cross-env MONITOR=1 npm run build:dev",
      "server:dev:monitor": "npm run clean:dist && cross-env MONITOR=1 npm run ng -- serve",
      "start:monitor": "npx mkdirp reports && cross-env MONITOR=1 npm run server:dev"
    }
  }
  ```

-Gives information about the bundle's size. This plugin is not enabled by default in Stark-Build so you need to pass the environment variable `MONITOR=1` to enable it.

-You can do this by setting the environment variable yourself before running the `ng serve` command or you can use [cross-env](https://github.com/kentcdodds/cross-env) and use it in an NPM script to set
-the environment variable temporarily only for this command:

-The WebpackMonitor app (for example: http://webpackmonitor.com/demo.html) showing all the bundles relevant information will be served automatically on port 3030.
-Also all the stats generated by WebpackMonitor will be available in a `stats.json` file under `reports/webpack-monitor`.

 #### [BundleAnalyzerPlugin](https://github.com/webpack-contrib/webpack-bundle-analyzer)
 
 Similar to WebpackMonitor, this plugin also gives information about the bundle's size with the difference that this is more interactive thanks to a zoomable tree map.
