It builds on#34872 for now.This PR allows using the PHP-DSL natively in our `Kernel::configureContainer()` methods.It allows the same in our `Kernel::configureRoutes()` methods.Both signatures are handled gracefully with no deprecations to let existing code in peace:- `protected function configureContainer(ContainerBuilder $c, LoaderInterface $loader);`- `protected function configureContainer(ContainerConfigurator $c);` (a loader is always passed as 2nd arg to ease FC)Same for routes:- `protected function configureRoutes(RoutingConfigurator $routes);`- `protected function configureRoutes(RouteCollectionBuilder $routes);` (this one is deprecated because `RouteCollectionBuilder` is deprecated)Here is my working `src/Kernel.php` after this change:```phpclass Kernel extends BaseKernel{    use MicroKernelTrait;    protected function configureContainer(ContainerConfigurator $container): void    {        $container->import('../config/{packages}/*.yaml');        $container->import('../config/{packages}/'.$this->environment.'/*.yaml');        $container->import('../config/services.yaml');        $container->import('../config/{services}_'.$this->environment.'.yaml');    }    protected function configureRoutes(RoutingConfigurator $routes): void    {        $routes->import('../config/{routes}/'.$this->environment.'/*.yaml');        $routes->import('../config/{routes}/*.yaml');        $routes->import('../config/routes.yaml');    }}```Commits-------cf45eec [FrameworkBundle] Allow using a ContainerConfigurator in MicroKernelTrait::configureContainer()
