Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires laravel/framework dev-master as 11 -> satisfiable by laravel/framework[dev-master]. - laravel/framework dev-master requires php ^8.3 -> your php version (8.2.27) does not satisfy that requirement. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
