Add ROCm 10.1.0 builds

[sreeram-11]

1. Pinned the pip install to ==${{ matrix.ROCM_VERSION }} on both Windows and Linux.
2. Converted windows-latest-rocm from job env: to a matrix, mirroring llama.cpp, and added a 10.1.0 leg to both the Windows and Linux ROCm matrices.
3. Fixed -DGPU_TARGETS="${{ env.GPU_TARGETS }}" → matrix.gpu_targets. The env var was named gpu_targets, and GPU_TARGETS was never defined.
4. Fixed the release artifact validator, which still checked for rocm-7.14.0 filenames that stopped existing when the repo moved to ROCm 10. It now iterates 10.0.0 10.1.0 across both platforms.
