Your requirements could not be resolved to an installable set of packages. Problem 1 - dnadesign/silverstripe-elemental[5.0.0-alpha1, ..., 5.x-dev] require php ^8.1 -> your php version (7.4; overridden via config.platform, actual: 7.4.33) does not satisfy that requirement. - Root composer.json requires dnadesign/silverstripe-elemental ^5.0 -> satisfiable by dnadesign/silverstripe-elemental[5.0.0-alpha1, ..., 5.x-dev].
