Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires orchestra/testbench ^10.0 -> satisfiable by orchestra/testbench[v10.0.0, v10.1.0, 10.x-dev]. - orchestra/testbench[v10.0.0, ..., 10.x-dev] require phpunit/phpunit ^11.5.3 -> found phpunit/phpunit[11.5.3, ..., 11.5.x-dev] but it conflicts with your root composer.json require (^10.4). Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
