Subject: [PATCH] fix(@schematics/angular): update library schematic to use
 `@angular-devkit/build-angular:ng-packagr`

The library schematic currently relies on Karma, which requires `@angular-devkit/build-angular` to be installed. To address this, we now use the `ng-packagr` builder provided in this package.

Closes #29494
