Your requirements could not be resolved to an installable set of packages. Problem 1 - doctrine/instantiator 2.0.0 requires php ^8.1 -> your php version (8.0.30) does not satisfy that requirement. - phpunit/phpunit 9.6.15 requires doctrine/instantiator ^1.3.1 || ^2 -> satisfiable by doctrine/instantiator[2.0.0]. - phpunit/phpunit is locked to version 9.6.15 and an update of this package was not requested.
