fix(@schematics/angular): don't add path mapping to old entrypoint definition file

With the APF changes in version 14, the dts entrypoint file has been changed to `index.d.ts`, this results in TypeScript being able to resolve the type definition file without the need of the additional path to the flat module file dts.

(cherry picked from commit e1ee636)
