Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires customgento/module-default-store-code-remover-m2 @dev -> satisfiable by customgento/module-default-store-code-remover-m2[dev-DEV-362-add-github-actions]. - customgento/module-default-store-code-remover-m2 dev-DEV-362-add-github-actions requires php ~7.3.0||~7.4.0||~8.1.0||~8.2.0 -> your php version (8.3.4) does not satisfy that requirement.
