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-jlamberts/

Start by opening the README and the repository settings where the description is managed. Replace both incorrect links with https://githubschool.github.io/github-games-jlamberts/ and verify that the README and repository description now point to that URL.
