Cuda 12.1 + Pytorch 2.31: Copy of Forge one-click Install package (Sept 2024)

A copy of Illyasviel's one-click installation package (but with Cuda 12.18 + Pytorch 2.7.1).

Kept here, in case the file changes URL in his repo.
The URL must remain the same, so that StableProjectorz installer can always download it.

Notice, the filename says cu121 for legacy reasons, but the contents are actually Cuda 12.8 + Pytorch 2.7.1
