`cuLibraryLoadData` raises `TypeError: 'int' object is not iterable`

[leofang]

This line is wrong:
https://github.com/NVIDIA/cuda-python/blob/b88592ae51c35af3bf1399a48d2180a6d9cec5cc/cuda/cuda.pyx.in#L21417
numJitOptions is an int, so it cannot be iterated over. What's should have been there in the zip is jitOptions.

I confirm this simple patch would make it work:

Fixed with 12.6 release, closing.
