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-rslibed

Update the repository description and README so both URLs point to https://githubschool.github.io/github-games-rslibed rather than githubschool's copy. Start by checking the current repository description and README link, then verify both references resolve to the requested game copy.
