Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/var-dumper 7.0.0 -> satisfiable by symfony/var-dumper[v7.0.0]. - symfony/var-dumper v7.0.0 requires php >=8.2 -> your php version (8.1.26) does not satisfy that requirement. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
