Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires matthiasnoback/symfony-config-test ^5.2 -> satisfiable by matthiasnoback/symfony-config-test[v5.2.0]. - matthiasnoback/symfony-config-test v5.2.0 requires symfony/config ^5.4 || ^6.2 || ^7.0 -> found symfony/config[v5.4.0, ..., v5.4.46, v6.2.0, ..., v6.4.28, v7.0.0, ..., v7.4.1] but these were not loaded, likely because it conflicts with another require.
