[good first issue] Review and clean up CONTRIBUTORS.md

[Cima9642]

📝 Description

As more contributors add themselves to Contributors.md, inconsistencies in
formatting can creep in. Help us keep it clean and consistent!

✅ What to do

• Fork the repo and create a branch
• Open Contributors.md and look for:
  • Entries missing GitHub links
  • Inconsistent formatting (extra spaces, wrong heading level, etc.)
  • Broken or malformed markdown links
• Fix any issues you find
• Open a Pull Request describing what you changed

Even fixing one small formatting issue counts — every contribution matters! 🎉
