Contributions summary:Joakim implemented and refined features related to platform package overrides within the Composer dependency manager. They added functionality to allow configuration of platform package overrides using the 'platform' setting and modified the `PlatformRepository` class to handle these overrides, including checking for platform package validity. The changes involved modifying the `Installer` and `Config` classes to integrate this new feature. They also added exception handling and restricted overrides to only platform packages.
