deps: bump PyTorch version to 1.12

[XuehaiPan]

Description

Update dependency PyTorch to 1.12 due to packaging issue for functorch. See functorch's release note: https://github.com/pytorch/functorch/releases/tag/v0.2.0 and issue pytorch/pytorch#80489.

Command:

CONDA_OVERRIDE_CUDA=11.7 conda env create --file conda-recipe.yaml
conda activate torchopt
pip3 install -e .

while create a dev environment with CUDA Toolkit 11.6.0, PyTorch (CUDA) 1.12.0, functorch 0.2, and JAX (CUDA) 0.3.14.

Stdout:

$ CONDA_OVERRIDE_CUDA=11.7 conda env create -f conda-recipe.yaml
