Fix pip command

[vidyasiv]

PyTorch/vLLM_Tutorials/FP8_Quantization_using_INC/FP8_Quantization_using_INC.ipynb notebook has:

pip install -r --quiet requirements-hpu.txt

This is incorrect as the -r expects the requirements file.

ERROR: Could not open requirements file: [Errno 2] No such file or directory: '--quiet'

This PR fixes the order of arguments.
