PR Description 📜

Hey @ayush-t02

• issue closes Bug in Contributors Data Fetching #712

I have fixed the bug in contributors data fetching

• fetchContributors: Fetches all contributors from the GitHub API and stores them in totalContributors.
• updateContributors: Updates the displayed contributors based on the current page and the number of contributors per page.
• Pagination: Adds event listeners to the "Previous" and "Next" buttons to navigate through pages, updating the contributors' display and enabling/disabling buttons as necessary.

This approach ensures that we display 30 contributors per page and navigate through them efficiently.
