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-mparikh-apttus

Open the repository description settings and the README, then compare both URLs with the target URL given in the issue. Update each reference to point to that game copy and verify that both links resolve to the repository's GitHub Pages address.
