Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires http-interop/http-factory-tests ^2.0.0 -> satisfiable by http-interop/http-factory-tests[2.0.0]. - http-interop/http-factory-tests 2.0.0 requires phpunit/phpunit ^10.0 -> found phpunit/phpunit[10.0.0, ..., 10.4.1] but it conflicts with your root composer.json require (^9.5.28). Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
