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-a00126165

Update the repository description and the URL in README; the issue provides the correct destination: https://githubschool.github.io/github-games-a00126165. Check both locations first, then confirm that neither still points to githubschool's copy and that both link to this repository's game.
