Add Hacktoberfest 2025 banner to README.md

[Akanksha-Patnaik]

Hi 👋 I came across this repo while looking for Hacktoberfest 2025 projects.

Could you please confirm if this repo is participating in Hacktoberfest 2025?

I noticed the README file doesn’t have the Hacktoberfest 2025 banner. May I include it if it’s okay?

Thank you! 😊
