Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/doctrine-bridge ^8.0.0 -> satisfiable by symfony/doctrine-bridge[v8.0.0]. - symfony/doctrine-bridge v8.0.0 requires php >=8.4 -> your php version (8.3.28) does not satisfy that requirement.
