resolve import problem of Catalyst 2.0 API

In order to link against catalyst::catalyst, the find_package needs to provide the GLOBAL keyword.
Then linkage, is working as well as the headers are found properly.
However the GLOBAL keyword is only available by CMake>=3.24 therefore also the bump up in the cmake_minimum_required.
