Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires drupal/core 11.1.x-dev -> satisfiable by drupal/core[11.1.x-dev]. - drupal/core 11.1.x-dev requires php >=8.3.0 -> your php version (8.2; overridden via config.platform, actual: 8.2.11) does not satisfy that requirement.

Process completed with exit code 2.
