147c88ef - Add docs to a pytorch.github.io/doc/tag directory when repo is tagged (#45204)

Add docs to a pytorch.github.io/doc/tag directory when repo is tagged (#45204) Summary: In coordination with jlin27. This PR is meant to build documentation when the repo is tagged. For instance, tagging the repo with 1.7.0rc1 will push that commit's documentation to pytorch/pytorch.github.io/docs/1.7. Subsequently tagging 1.7.0rc2 will override the 1.7 docs, as will 1.7.0, and 1.7.1. I think this is as it should be: there should be one, latest, version for the 1.7 docs. This can be tweaked differently if desired. There is probably work that needs to be done to adjust the [versions.html](https://pytorch.org/docs/versions.html) to add the new tag? Is there a way to test the tagging side of this without breaking the production documentation? As an aside, the documentation is being built via the `pytorch_linux_xenial_py3_6_gcc5_4_build` image. Some projects are starting to move on from python3.6 since [it is in security-only support mode](https://devguide.python.org/#status-of-python-branches), no new binaries are being released.
