Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires nyholm/symfony-bundle-test ^2.0 -> satisfiable by nyholm/symfony-bundle-test[2.0.0]. - nyholm/symfony-bundle-test 2.0.0 requires symfony/dependency-injection ^4.4 || ^5.3 || ^6.0 -> found symfony/dependency-injection[v4.4.0, ..., v4.4.49, v5.3.0, ..., v5.4.33, v6.0.0, ..., v6.4.1] but these were not loaded, likely because it conflicts with another require.
