Typo in download link for NVHPC 20.11 for SBSA/Arm64

There seems to be a typo on the download page for NVIDIA HPC SDK 20.11, for SBSA architecture, for the multi-CUDA version. It still says x86_64 even though the wget line is correct.

Thanks for pointing this out. If alerted the folks who maintain this page and ask them to update.
