Pull request overview

This PR updates the repo’s pinned PyTorch XPU dependency to Torch 2.11 and adjusts CI to install from the PyTorch XPU test wheel index, seemingly to validate compatibility ahead of a stable release.

Changes:

• Switch Torch pin from 2.10.0+xpu to 2.11.0+xpu in both requirements.txt and pyproject.toml.
• Change the PyTorch wheel source from the stable XPU index to the whl/test/xpu index.
• Update the unit test workflow to build/run using a xpu-kernel-ci-image:test-211 Docker tag and install with the test XPU index.

The workflow no longer tags/pushes xpu-kernel-ci-image:latest (it now only produces :test-211). Downstream workflows (e.g. wheel-per-commit.yaml) still run in localhost:5000/xpu-kernel-ci-image:latest, so they’ll keep using a stale image or fail if :latest doesn’t exist on the runner. Consider continuing to tag/push :latest as well, or update all dependent workflows to use :test-211 consistently.
