Subject: [PATCH] refactor(migrations): exclude all @angular/* packages from
 schematics bundle

This change updates the rollup configuration for the core schematics to exclude all `@angular/*` packages from the bundle. This is possible following https://github.com/angular/angular/pull/64703

This significantly reduces the size of the `@angular/core` schematics bundle, resulting in a size reduction to 5.8mb.
