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-dbucke

Update the repository description and README so both URLs point to https://githubschool.github.io/github-games-dbucke. Start by checking the README and the repository's description, then verify that each link resolves to this copy of the game; done means neither location points to githubschool's other copy.
