Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires phpunit/phpunit ^11.2.8 -> satisfiable by phpunit/phpunit[11.2.8, 11.2.x-dev, 11.3.x-dev].
- phpunit/phpunit[11.2.8, ..., 11.3.x-dev] require php >=8.2 -> your php version (7.4.33) does not satisfy that requirement.
