COMP: Re-enable CI with system package inputs for OpenSlide

Re-enable build workflows using new inputs from
ITKRemoteModuleBuildTestPackageAction:
- apt-packages: install libopenslide-dev on Linux
- brew-packages: install openslide on macOS
- os-list: skip Windows (no OpenSlide package manager distribution)

Python wheel builds re-enabled with default configuration.

Also updates minimum Python version to 3.10+.
