Problems with Step 1: Add UI Shell

Is the tutorial still up to date?

https://www.carbondesignsystem.com/developing/angular-tutorial/step-1#add-ui-shell

At some point during this step, we need to import the icons from our @carbon/icons package like:

import Notification16 from '@carbon/icons/es/notification/16';
import UserAvatar16 from '@carbon/icons/es/user--avatar/16';
import AppSwitcher16 from '@carbon/icons/es/app-switcher/16';

But when I look into the files at GitHub, it looks like newer carbon components are used, for example:

import { Notification20Module } from '@carbon/icons-angular/lib/notification/20';
import { UserAvatar20Module } from '@carbon/icons-angular/lib/user--avatar/20';
import { AppSwitcher20Module } from '@carbon/icons-angular/lib/app-switcher/20';

Compare the tutorial's Step 1: Add UI Shell page with the current files in the carbon-tutorial-angular repository, focusing on the icon imports shown in the issue. Verify whether the tutorial uses the older @carbon/icons imports while the application uses @carbon/icons-angular modules. Done means the tutorial instructions match the current implementation, or the discrepancy is documented clearly.
