Prior to this patch, the release process (`pip wheel`) retrieved
dependencies from the pyproject.toml file, which specified a version of
PyTorch that defaulted to the most recent nightly release. Instead, we
want the release process to use the same pinned PyTorch version as the
development build of PyTorch.
Since TOML files can't reference the pytorch-requirements.txt file, this
patch puts the dependencies from pyproject.toml into
whl-requirements.txt, which references pytorch-requirements.txt.
