Description

There's a bug occurring when attempting to build an Angular package using the latest version of ng-packagr (17.2.1).

How To Reproduce

To reproduce the bug:

1. Create an Angular package with sub entries.
2. Within the nested ng-package.json files, include a property named "dest".
3. Attempt to build the package.
4. Error occurs during the build process.

It seems that a schema validation error for nested sub entries has surfaced after version 17.0.3. Attached is a reproducible example.

Expected Behaviour

The package should build successfully even when the "dest" property is present in ng-package.json for packages with sub entries.
