URL in description and README broken

The URL in the repository description and the one in the README are pointing to githubschool's copy of the game instead of yours.

Please fix both so they point to your copy of the game at https://githubschool.github.io/github-games-MithunPoojary

Check the repository description settings and the README for the two incorrect URLs. Update both references to the repository's GitHub Pages URL, then review the rendered README and repository header to confirm each link points to the requested copy of the game.
