Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires pestphp/pest-plugin-laravel 3.0.0 -> satisfiable by pestphp/pest-plugin-laravel[v3.0.0]. - pestphp/pest-plugin-laravel v3.0.0 requires laravel/framework ^11.22.0 -> found laravel/framework[v11.22.0, ..., v11.44.0] but it conflicts with your root composer.json require (12.*).
