[documentation of Upgrading from AngularJS to Angular] libraries to load in the browser

[eetievent]

Description

When upgrading from AngularJS to Angular, it may be needed to declare the libraries to load in the browser in angular.js / build.options.scripts , including angular.js.
This could be added to the documentation? (Indeed the examples given are based on SystemJS but we don't use it because Angular uses already Webpack).

What's the affected URL?

https://angular.io/guide/upgrade#bootstrapping-hybrid-applications

Reproduction Steps

upgrade to AngularJS 1.7
remove Grunt and use angular-cli
use ngUpgrade (app.module.ts and app.module.ajs.ts)
removed require("angular") (use of the AngularJS global angular)

🔥 Exception or Error

Angular 1.x not loaded !
generated by this.upgrade.bootstrap(document.body, [App])

Anything else relevant?

The official docs do not use (or assume) the use of @angular/cli (or webpack) yet (unfortunately) and that is the main issue. (This is mostly because the cli wasn't a thing back when the docs where created.)

I know it is on the roadmap to update the ngUpgrade docs and show a cli-based/-compatible approach (but is not a high priority atm).
@jenniferfell, is this tracked tracked somewhere?

I would suggest to state explicitly that the doc is based on SystemJS and that the use of the @angular/cli is not documented yet. Thank you.
