Your requirements could not be resolved to an installable set of packages. Problem 1 - drupal/test_support dev-1.0.x requires drupal/core ^9.1 || ^10 -> found drupal/core[9.1.0-alpha1, ..., 9.5.x-dev, 10.0.0-alpha1, ..., 10.4.x-dev] but these were not loaded, likely because it conflicts with another require. - drupal/test_support 1.0.x-dev is an alias of drupal/test_support dev-1.0.x and thus requires it to be installed too. - Root composer.json requires drupal/test_support ^1 -> satisfiable by drupal/test_support[1.0.x-dev (alias of dev-1.0.x)].
