Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires roots/wordpress dev-nightly, found roots/wordpress[dev-main, 3.7.38, ..., 3.9.40, 4.0, ..., 4.9.26, 5.0, ..., 5.9.10, 6.0, ..., 6.6] but it does not match the constraint. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
