Description

This PR addresses 9 accessibility violations (#6871) identified by IBM Equal Access Accessibility Checker in the "Who's using recharts?" section. The fix removes redundant alt text from logo images that are already accompanied by visible text labels within the same link, improving the experience for screen reader users by eliminating unnecessary repetition.

#6871

The accessibility checker identified 9 instances of redundant image alternative text:
Violations found:

• "The text alternative for an image within a link should not repeat the link text or adjacent link text"
• Affected logos: ShadeUI, EvilCharts, 阿里指数, 阿里数据, Fyndiq, chayns, Demisto, Squadlytics, ahrefs

Motivation and Context

Changed the image alt attribute from alt={entry.name} to alt="" (empty string), making the images decorative:

<a href={entry.url} target="_blank" title={entry.name} rel="noreferrer">
  <img src={entry.logoImgUrl} alt="" />
  <span className="user-name">{entry.name}</span>
</a>

Why empty alt (alt="") is correct:

• The visible text span already provides the accessible name for the link
• The logo image is decorative within this context (it doesn't add unique information)
• Empty alt tells screen readers to skip the image, avoiding redundancy
• The link's title attribute still provides hover tooltip for mouse users

Note: We also removed the redundant title={entry.name} from the <img> tag as it served no purpose and could cause additional tooltip clutter.
