Match CUDA_VER to TORCH_CUDA in nightly pytorch matrix

CUDA_VER in the test environment should match TORCH_CUDA in
major.minor. BUILD_CUDA_VER (from build-ctk-ver input) is used
for artifact names, so CUDA_VER can differ.

- cu126 → CUDA_VER: 12.6.3 (was 12.9.1)
- cu130 → CUDA_VER: 13.0.2 (was 13.2.1)

For CUDA 12 entries, USE_BACKPORT_BINDINGS kicks in automatically
since BUILD_CUDA_MAJOR (13) \!= TEST_CUDA_MAJOR (12), pulling
bindings from the backport branch.
