Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit 11.5.2 -> satisfiable by phpunit/phpunit[11.5.2]. - phpunit/phpunit 11.5.2 requires php >=8.2 -> your php version (8.1.31) does not satisfy that requirement. Problem 2 - Root composer.json requires orchestra/testbench ^7.0 -> satisfiable by orchestra/testbench[v7.0.0, ..., 7.x-dev]. - orchestra/testbench[v7.0.0, ..., 7.x-dev] require phpunit/phpunit ^9.5.10 -> found phpunit/phpunit[9.5.10, ..., 9.6.x-dev] but it conflicts with your root composer.json require (11.5.2).
