Fix format of CUDA classifier used for upload to PyPi
BTW this may not even fix it as the classifier for 12.2 is not even listed on https://pypi.org/classifiers/ yet, but at least it would be correct for when it does appear.
For CUDA 12 there is an extra field in the classifier so add that in to fix the upload failures.
