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-pwatsonr

Update the repository description and the URL in README so both point to the repository's own game copy at the URL given in the issue. Check both locations after editing and confirm neither still points to githubschool's copy.
