Update antiqated pytorch for AI-Toolkit #1714

Proposal

AI toolkit asks for pytorch 2.13. Stability matrix still uses 2.9.
2.13 should be the default since it has a lot of improvements like better memory management. That is very usefull when trying to train video models on a consumer card

From their instalation script

pip3 install --no-cache-dir torch==2.13.0 torchvision==0.28.0 torchaudio==2.11.0 --index-url https://download.pytorch.org/whl/cu130
