Remove incorrect links to zdevito/ATen (#50065)
Summary:
Similar to https://github.com/pytorch/pytorch/issues/49028, this PR removes a few more references to https://github.com/zdevito/ATen.
- The links for Functions.h, Tensor.h, and Type.h are simply broken, probably because they refer to `master` rather than a specific commit (cf. https://github.com/pytorch/pytorch/issues/47066)
- I'm unsure about the change to the `about` section of `aten/conda/meta.yaml`; can someone comment on whether I am understanding that field correctly?
- The reference to https://github.com/zdevito/ATen/issues/163 remains [in `tools/autograd/derivatives.yaml`](https://github.com/pytorch/pytorch/blob/cd608fe59b70fa7cafb07110096b2e023a8b6e9c/tools/autograd/derivatives.yaml#L91), because the contents of that issue discussion don't seem to be mirrored anywhere else.
