Your requirements could not be resolved to an installable set of packages. Problem 1 - codeception/codeception[5.0.0, ..., 5.0.10] require php ^8.0 -> your php version (7.4.33) does not satisfy that requirement. - Root composer.json requires codeception/codeception ^4.0 || ^5.0 -> satisfiable by codeception/codeception[5.0.0, ..., 5.0.10].
