Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires ghostwriter/coding-standard dev-main -> satisfiable by ghostwriter/coding-standard[dev-main]. - ghostwriter/coding-standard dev-main requires php ^8.2 -> your php version (8.1.999; overridden via config.platform, actual: 8.4.3) 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.
