pytorch: rename pytorch-version.txt to pytorch-hash.txt (llvm#1541)

This patch is part of a larger set of improvements to the CI/build
system.  In the code, we refer to the version as the string that
contains the release identifier such as 1.14.0.dev20221028, so calling
the file that contains the commit hash as pytorch-version.txt creates
confusion.  For the sake of simplicity, this patch renames that file to
be pytorch-hash.txt.
