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-ndoddi-apttus

Update the repository description and the URL in README, both of which are identified in the issue. Replace the githubschool copy link with https://githubschool.github.io/github-games-ndoddi-apttus, then check the rendered README and repository page to confirm both links point to the project copy.
