Your requirements could not be resolved to an installable set of packages.
Problem 1
- orchestra/testbench[v8.0.0, ..., v8.19.0] require php ^8.1 -> your php version (8.0.30) does not satisfy that requirement.
- Root composer.json requires orchestra/testbench ^8.0 -> satisfiable by orchestra/testbench[v8.0.0, ..., v8.19.0].
