Suggestion: Using pre-built PyTorch Scatter from its official

[YanWenKun]

As described in the PyTorch Scatter's doc, instead of compile-install, we can install its official binaries:

python3 -m pip install \
  torch-scatter --find-links https://data.pyg.org/whl/torch-2.2.2+cu121.html

I guess maybe we could change the item in requirements_post.txt ? I mean, building PyTorch Scatter is really slow...

Yeah, I'll take it look and change it in the next update. cheers👍
