Updates for all angular.io links to the new angular.dev domain. Additionally, adjustment to new resources where the equivalent does not exist on the new site (e.g. Tour of Heroes tutorial)
These async methods are a replacement for the Observable based `runSchematicAsync` and `runExternalSchematicAsync` methods.
DEPRECATED:
The Observable based `SchematicTestRunner.runSchematicAsync` and `SchematicTestRunner.runExternalSchematicAsync` method have been deprecated in favor of the Promise based `SchematicTestRunner.runSchematic` and `SchematicTestRunner.runExternalSchematic`.
Prior to this commit, we defined routes in two places example:
```ts
@NgModule({
declarations: [
HomeComponent
],
imports: [
CommonModule,
RouterModule.forChild(routes),
HomeRoutingModule
]
})
export class HomeModule { }
```
Closes#17139
All TypeScript files have been updated to pass the new eslint-based linting checks. eslint compatible disabling comments have also been added in place of the previous tslint comments.
