Your requirements could not be resolved to an installable set of packages.
Problem 1
- phpunit/phpunit[10.0.0, ..., 10.5.16] require php >=8.1 -> your php version (8.0.30) does not satisfy that requirement.
- Root composer.json requires phpunit/phpunit ^10.0 -> satisfiable by phpunit/phpunit[10.0.0, ..., 10.5.16].
