The job was canceled because "ubuntu-latest_8_1" failed.

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpdocumentor/reflection ~6.0.0 -> satisfiable by phpdocumentor/reflection[6.0.0]. - phpdocumentor/reflection 6.0.0 requires php 8.1.*|8.2.*|8.3.* -> your php version (7.2.34) does not satisfy that requirement.
