The job was canceled because "highest_8_3_ubuntu-latest" failed.

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit ^11.0.0 -> satisfiable by phpunit/phpunit[11.0.0, ..., 11.0.6]. - phpunit/phpunit[11.0.0, ..., 11.0.6] require php >=8.2 -> your php version (8.1.99; overridden via config.platform, actual: 8.1.27) does not satisfy that requirement. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
