ADD HACKTOBEFEST BANNER ON THE README

[alo7lika]

Issue Description

The README currently does not include the official Hacktoberfest banner, which is essential to indicate that this repository is participating in Hacktoberfest clearly. The inclusion of the Hacktoberfest banner will attract contributors and highlight the repository's participation in this open-source event.

Expected Outcome A visually appealing Hacktoberfest banner should be added at the top section of the README. The banner should follow Hacktoberfest guidelines for image usage and branding. The banner should link to the official Hacktoberfest website to provide additional context for potential contributors.
