xpu/cpu: docker images referenced in documentation do not exist

[dvrogozh]

xpu and cpu Intel images referenced in documentation do not exist:

• https://huggingface.co/docs/text-generation-inference/en/installation_intel
• https://github.com/huggingface/text-generation-inference/blob/main/docs/source/installation_intel.md

$ docker pull ghcr.io/huggingface/text-generation-inference:2.2.0-intel-cpu
Error response from daemon: manifest unknown
(pytorch.xpu) dvrogozh@willow-spr03:~/git/huggingface/text-generation-inference$ docker pull ghcr.io/huggingface/text-generation-inference:2.2.0-intel-xpu
Error response from daemon: manifest unknown

That's regression after this PR got merged 3 weeks ago:

• update doc with intel cpu part #2420

since older named image does exist:

$ docker pull ghcr.io/huggingface/text-generation-inference:2.2.0-intel

Also, considering that the PR did propose a name change for Intel image. Can instruction and docker images clearly reflect that these images are IPEX based? Please note that XPU support is available in upstream pytorch and it's actually confusing to download image with the generic XPU name in it to find out that it actually has IPEX inside.

try
docker pull ghcr.io/huggingface/text-generation-inference:latest-intel-xpu

and
docker pull ghcr.io/huggingface/text-generation-inference:latest-intel-cpu

try
docker pull ghcr.io/huggingface/text-generation-inference:latest-intel-xpu

@sywangyi : these two commands work, but they are not documented either.
