vLLM component image doesnt work out of the box

[amberjain1]

The vLLM image in OPEA doesn't work due to a known bug in vLLM (HabanaAI/vllm-fork#462).

The steps mentioned to compile the vLLM image mentions that we need to use setuptools=69.5.1 version. But that statement doesn't exist in the dockerfile.hpu.
(sed -i "s/RUN pip install setuptools/RUN pip install setuptools==69.5.1/g" docker/Dockerfile.hpu)

Please clean up the documentation so that the build goes smoothly. Also, push a valid image in opea harbour.
