Your requirements could not be resolved to an installable set of packages.
Problem 1
- orchestra/testbench[v7.33.0, ..., 7.x-dev] require laravel/framework ^9.52.15 -> found laravel/framework[v9.52.15, v9.52.16, 9.x-dev] but it conflicts with your root composer.json require (8.x).
- orchestra/testbench 8.x-dev requires php ^8.1 -> your php version (8.0.30) does not satisfy that requirement.
- Root composer.json requires orchestra/testbench ^7.33 || ^8.14 -> satisfiable by orchestra/testbench[v7.33.0, 7.x-dev, 8.x-dev].
