Add Contributor's Section to the Website

# **Description:**
We'd love to showcase the amazing people contributing to SimplifAI! Create a section (in the last of **About page** ) that displays a list of contributors.

You can either:
- Use the **GitHub API** to dynamically fetch contributors.
- Or create a **static JSON file** to list names, GitHub profiles, and optionally, profile pictures.

**Suggested Layout:**
- Name or GitHub username
- Profile picture
- Link to GitHub profile

**Design Tips:**
- Keep it clean and responsive.
- Must match the website theme
- Use shadcn and other supporting lib
- You can use cards, avatars, or a simple grid layout.
