Small issue in the steps to create the app from sample DB schema - Windows

[mamukundan]

In Windows, the below step doesn't work (doesn't delete the files) and it doesn't complain either

rm web/src/app/app.module.ts web/src/app/app.component.* web/src/styles.css

Due to this the quickstart doesn't work as expected. Once the files were deleted manually, the application started working.
