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 (8.1.29) does not satisfy that requirement.
Problem 2
- orchestra/testbench[v7.0.0, ..., v7.42.2] require phpunit/phpunit ^9.5.10 -> found phpunit/phpunit[9.5.10, ..., 9.6.19] but it conflicts with your root composer.json require (^10.5|^11.0).
- Root composer.json requires orchestra/testbench 7.* -> satisfiable by orchestra/testbench[v7.0.0, ..., v7.42.2].
