Your requirements could not be resolved to an installable set of packages. Problem 1 - doctrine/collections[2.1.0, ..., 2.3.x-dev] require php ^8.1 -> your php version (8.0.30) does not satisfy that requirement. - Root composer.json requires doctrine/collections ^2.1 -> satisfiable by doctrine/collections[2.1.0, ..., 2.3.x-dev].
