Your requirements could not be resolved to an installable set of packages. Problem 1 - magento/product-community-edition is locked to version 2.4.6 and an update of this package was not requested. - magento/product-community-edition 2.4.6 requires ext-bcmath * -> it is missing from your system. Install or enable PHP's bcmath extension. Problem 2 - Root composer.json requires sequra/magento2-core dev-3.0.0-alpha-add-integrations-tests -> satisfiable by sequra/magento2-core[dev-3.0.0-alpha-add-integrations-tests]. - sequra/magento2-core dev-3.0.0-alpha-add-integrations-tests requires sequra/integration-core dev-CR-SET-04-01 -> found sequra/integration-core[dev-CR-SET-04-01] but it does not match your minimum-stability.
