Reverts #49's dictionary→category mapper and excludes the buggy pandas version in metadata (pandas>=2.0,!=2.2.*) instead. pandas 2.2.x crashes on pivot() over ArrowDtype dictionary columns ("'Series' object has no attribute '_pa_array'", fixed upstream in 2.3). The exclusion keeps the code simpler and also protects users from hitting the same pandas bug in their own code on the ArrowDtype dictionary frames triplets hands them — a code workaround only fixed our internal paths.
