Description

This PR releases the new Hugging Face PyTorch DLC for Inference with a bunch of version dumps for transformers, diffusers and sentence-transformers; as well astorchand other dependencies that otherwise could be problematic as the latesthuggingface_hubrelease affectingdiffusers` <= 0.30.0

Some of the changes in this PR include:

• Include missing requirements.txt installation in entrypoint.sh (required to install custom dependencies with custom models).
• Fix uvicorn trigger on the entrypoint.sh to use exec so that the process runs with PID 1, allowing it to receive signals directly; and so on, to be gracefully shut down.
• Fix Python 3.11 installation as it was not properly installed and Python 3.10 was used instead; also fix pip installation to install via get-pip.py.
• Tested with some of the latest models that those bumped dependencies support as Gemma2, Llama3.2, StableDiffusion 3.5, and much more.
