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-RachelDillinger

Start by checking the repository description and README, which are the two locations named in the issue. Update both URLs to the specified game copy, then verify that each link resolves to the repository's GitHub Pages URL.
