Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires cviebrock/eloquent-sluggable 10.0.0 -> satisfiable by cviebrock/eloquent-sluggable[10.0.0]. - cviebrock/eloquent-sluggable 10.0.0 requires php ^8.1 -> your php version (8.0.30) does not satisfy that requirement.
