[Docs]: Fix incorrect index usage in vector_add example in documentation

[XXXXRT666]

Description

The example kernel in the documentation uses C[tid] = A[tid] + B[tid] inside a loop, which should instead be C[i] = A[i] + B[I], to correctly handle strided indexing across threads.

Thanks for catching the issue @XXXXRT666, LGTM! It seems we only caught the issue partially in #582. FWIW this bug also exists in the sample https://github.com/NVIDIA/cuda-python/blob/main/cuda_core/examples/vector_add.py on which the doc is based, would you like to fix it as well?

Also please kindly add a release note entry to cuda_core/docs/source/release/0.X.Y-notes.rst 🙂

I think I have fixed all the [C[tid] = A[tid] + B[tid] problems now. Thanks!

Also please kindly add a release note entry to cuda_core/docs/source/release/0.X.Y-notes.rst 🙂

Done
