The "2.0" constraint for "psr/http-message" appears too strict and will likely not match what you want. See https://getcomposer.org/constraints

Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires czproject/git-php v4.5.0 -> satisfiable by czproject/git-php[v4.5.0].
- czproject/git-php v4.5.0 requires php 8.0 - 8.4 -> your php version (8.5.0) does not satisfy that requirement.
Installation failed, reverting ./composer.json to its original content.
