Fix stale Intel Arc driver links breaking README hyperlink check

[Copilot]

Description

The README hyperlink validation job was failing on a dead Intel GPU driver documentation URL referenced by the EdgeCraftRAG Intel Arc docs. This updates the stale link to the current Intel docs path in both the English and Chinese README variants.

• Root cause

  • check-the-validity-of-hyperlinks-in-README failed on installation-rolling.html#installing-gpu-drivers, which now returns 404.

• Change

  • Updated the Intel Arc A770 driver documentation link in:
    • EdgeCraftRAG/docker_compose/intel/gpu/arc/README.md
    • EdgeCraftRAG/docker_compose/intel/gpu/arc/README_zh.md

- https://dgpu-docs.intel.com/driver/installation-rolling.html#installing-gpu-drivers
+ https://dgpu-docs.intel.com/driver/installation.html#installing-gpu-drivers
