Re-writing README-HI.md

Author: Kumarutkarsh9470Created May 12, 2025Updated May 12, 2025

Hello maintainers, I have re-written the README-HI.md file with better proficiency and much more explanation.

Things I have improved :

  1. Better language proficiency for native language user to understand.
  2. Description of each topic and subtopics within it.
