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-deanstavro

Check the URL in the README and the repository description. Update both to https://githubschool.github.io/github-games-deanstavro, then verify that each link points to this repository's game copy.
