fix: add accessible label to icon-only link (#96334)
## Summary
This PR improves the accessibility of the Ant Design example by adding
an accessible label to the icon-only `Link`.
### Changes
- Added `aria-label="Home"` to the icon-only link.
### Why
The link currently renders only an icon, so it does not provide an
accessible name for assistive technologies. Adding an `aria-label` makes
its purpose clear to screen reader users without changing the visual
appearance.
### Before
Screen readers announce the element as an unlabeled link.
### After
Screen readers announce the link as **"Home"**.
