Description

ng update @angular/cli@9 updates @angular-devkit/build-angular and tslib to latest version ("@angular-devkit/build-angular": "~0.1000.0" & "tslib": "^2.0.0") starting from a project with latest 8.x version.

🔬 Minimal Reproduction

I followed the 'During the update' steps from the Angular Update Guide.

1. So I run ng update @angular/core@8 @angular/cli@8 in my workspace directory to update to the latest 8.x version.
2. I created a git commit
3. I tried to update to version 9 of Angular by running ng update @angular/core@9 @angular/cli@9.
4. My project has now been updated to TypeScript 3.8.x
5. "@angular-devkit/build-angular": "~0.1000.0" & "tslib": "^2.0.0" are installed
