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-mukul1689

Open the README and the repository description, then compare both URLs with the requested game URL. Update each link so it points to https://githubschool.github.io/github-games-mukul1689, and verify that both locations show the corrected destination.
