Doctrine ORM documentation V3 and V4

the DI container definition Entitymanager does too much. So It’s preferable to create an another one for the connexion (EntityManager and cache (slim 4) - #2 by odan)

// connexion à la base de données
    Connection::class => function (ContainerInterface $container) {
        $settings = (array)$container->get('settings')['doctrine'];
        // paramètres de connexion
        $dbParams = $settings['connectionMysql'];
        $config = $container->get('doctrineConfig');
        return DriverManager::getConnection($dbParams, $config);
    },

    //Configuration
    'doctrineConfig' => function (ContainerInterface $container) {
        $settings = (array)$container->get('settings')['doctrine'];
        return ORMSetup::createAttributeMetadataConfiguration(
            [$settings['pathToModels']], //chemin des l'entités
            $settings['isDevMode'] //est-on en développement?
        );
    },

    //EntityManager
    EntityManager::class => function (ContainerInterface $container) : EntityManager {
        $settings = (array)$container->get('settings')['doctrine'];
        $cache = $settings['isDevMode'] ?
            new ArrayAdapter() : 
            new FilesystemAdapter(directory: $settings['cache_dir']);
        $connection = $container->get(Connection::class); 
        $config = $container->get('doctrineConfig');
        return new EntityManager($connection, $config);
