* This script updates a package.json file by replacing all dependencies and devDependencies
* such that all packages from the @angular scope point to the packages-dist directory.
*
* Please be aware that updating of versions might introduce compatibility issues. For instance,
* if a peer dependency of Angular, e.g. "typescript" changes, the package.json that is updated
* by this script will not have updated the "typescript" dependency to satisfy the peer dependency
* requirement. As a result, incompatibility errors might occur.
