ErrorHandler docs don't have standalone alternative

Describe the problem that you experienced

We haven't added docs on how to use ErrorHandler without NgModules https://angular.dev/api/core/ErrorHandler?tab=usage-notes

Add documentation on how to use ErrorHandler without NgModules in the app config:

export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    { provide: ErrorHandler, useClass: GlobalHandler },
  ],
};

Please also document how to add an ApplicationConfig to an app that doesn't have one.

• https://angular.dev/api/platform-browser/ApplicationConfig# is deprecated, but doesn't link to its replacement
• https://angular.dev/api/core/ApplicationConfig# doesn't say how to add one.

@fredsa While better linking would indeed be better, what you are looking for is here : https://angular.dev/api/platform-browser/bootstrapApplication
