Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires laminas/laminas-mvc ^3.8.0 -> satisfiable by laminas/laminas-mvc[3.8.0]. - laminas/laminas-mvc 3.8.0 requires laminas/laminas-servicemanager ^3.20.0 -> found laminas/laminas-servicemanager[3.20.0, ..., 3.23.0] but it conflicts with your root composer.json require (^4.0.0). Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
