The job was canceled because "_8_2__7_0_--prefer-lowest" failed.

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit ^12.0 -> satisfiable by phpunit/phpunit[12.0.0]. - phpunit/phpunit 12.0.0 requires php >=8.3 -> your php version (8.2.27) does not satisfy that requirement.
