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-git-for-shubh

Open the README and inspect the repository description in the GitHub repository settings. Replace both outdated links with the specified game URL, then verify the README link and description resolve to the repository's copy.
