Documentation lack necessary code example to fully work

[Sorikairox]

Controllers' page lack bootstrap code to run the app

https://savory.github.io/Danet/first-steps/controllers/

Need to add

import { AppModule } from './app.module.ts';
import { DanetApplication } from './deps.ts';

export const bootstrap = async () => {
  const application = new DanetApplication();
  await application.init(AppModule);
  return application;
}
