Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires php ^8.2 but your php version (8.1.32) does not satisfy that requirement.
Problem 2
- Root composer.json requires orchestra/testbench ^8.2.0 -> satisfiable by orchestra/testbench[v8.2.0, ..., 8.x-dev].
- orchestra/testbench[v8.4.0, ..., v8.33.0] require phpunit/phpunit ^9.6 || ^10.1 -> found phpunit/phpunit[9.6.0, ..., 9.6.x-dev, 10.1.0, ..., 10.5.x-dev] but it conflicts with your root composer.json require (^11.0).
- orchestra/testbench[v8.2.0, ..., v8.3.1] require phpunit/phpunit ^9.6 || ^10.0.7 -> found phpunit/phpunit[9.6.0, ..., 9.6.x-dev, 10.0.7, ..., 10.5.x-dev] but it conflicts with your root composer.json require (^11.0).
- orchestra/testbench[v8.34.0, ..., 8.x-dev] require phpunit/phpunit ^9.6|^10.1 -> found phpunit/phpunit[9.6.0, ..., 9.6.x-dev, 10.1.0, ..., 10.5.x-dev] but it conflicts with your root composer.json require (^11.0).
