Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires typo3/testing-framework ^6.16.7 -> satisfiable by typo3/testing-framework[6.16.7, 6.16.8, 6.16.9]. - typo3/testing-framework[6.16.7, ..., 6.16.9] require typo3/cms-core 10.*.*@dev || 11.*.*@dev -> found typo3/cms-core[v10.0.0, ..., 10.4.x-dev, v11.0.0, ..., 11.5.x-dev] but it conflicts with your root composer.json require (^12.2.0 || 12.3.x-dev || dev-main).
