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-DanCobb1111

Update the URL in the README and the repository description to the specified GitHub Pages address. Start by opening README and the repository settings, then verify that both locations point to https://githubschool.github.io/github-games-DanCobb1111.
