Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires omines/antispam-bundle ^0.1 -> satisfiable by omines/antispam-bundle[0.1.0, 0.1.1, 0.1.2, 0.1.x-dev]. - omines/antispam-bundle[0.1.0, ..., 0.1.x-dev] require php >=8.1 -> your php version (7.4.33) does not satisfy that requirement.
