Protractor `elementExplorer` debugger and element explorer cannot be used for Node.js 8+ since it relied on `_debugger` module.
In protractor version 5, this resulted in the below error:
```

but in protractor version 7, this logic was removed.
BREAKING CHANGE:
Protractor builder elementExplorer option has been removed. This was not compatable with the Node.Js versions that the Angular CLI supports. See: https://github.com/angular/protractor/blob/master/docs/debugging.md#enabled-control-flow for an alternative debugging methods.
BREAKING CHANGE:
Removed deprecated `typescriptMismatch` warning option. Users will be migrated off this option automatically. Users wishing to disable TypeScript version checks should use the Angular compiler option `disableTypeScriptVersionCheck`, see https://angular.io/guide/angular-compiler-options#disabletypescriptversioncheck for more information.
