I have verified with NVDA that aria-description works.

研究方向
The bug is that the accessibility checker in Storybook's addon a11y does not recognize the valid ARIA attribute `aria description`. To fix, locate the file that defines the list of valid ARIA attributes (likely in the addon a11y package, e.g., `addons/a11y/src/constants.ts` or similar). Add `aria description` to that list. Verify using the MDN documentation linked in the issue. No other changes are needed; this is a localized addition.
