[PyTorch] Break up generated tag in source (#56503)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/56503
The presence of `generated` causes Phabricator and hg to think the file is generated (e.g., hg won't prompt to resolve merge conflicts with an editor). Breaking up the tag is the traditional way to solve this.
