This PR adds a new workflow that runs unit tests on the latest stable torch release and the nightly release. The nightly is a scheduled workflow and runs once daily on main DeepSpeed branch.
Also addresses #1987 by extending torch information stored in
deepspeed.git_version_info.torch_info. This was necessary to avoid initializing CUDA withtorch.cuda.is_bf16_supported()before a distributed unit test whenbf16_required_version_check()was used.
