Sets up a minimal CLI project for testing that `ng add @angular/localize`
works as expected. Schematic sub-packages are prone to CJS/ESM issues
due the overall framework packages being denoted as strict ESM.
This may not be an issue in the concrete scenario of `@angular/localize`
right now, but it is still good to have an integration test similar to
the tests we have for `@angular/core` schematics.
