I was looking into issue #6 and noticed from the codebase that it is currently well-structured and uses the API endpoint /api/v2/issues. That API path even corresponds to the new API (v2) mentioned in the issue, thus no changes to the API path were needed. However, the actual structure of the response data from /api/v2/issues had changed, so i thought we might need to update the JavaScript code accordingly. So I tried to make some changes.

Key Enhancements

1. ApiEndpoint.java

   • I updated the /api/v2/contributors endpoint to include metadata like the number of contributions.
   • I added logging for better debugging and traceability.

2. index.html

   • I added a prominent link to the contributors' page for seamless navigation.

3. contributors.html

   • I enhanced error handling for failed contributor data fetch operations.
   • I displayed additional metadata, such as the number of contributions, alongside each contributor's avatar and username.
   • I improved layout and responsiveness for a better user experience.
