URL in description and README broken

The URL in the repository description and 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-SallyNashed/

Open the README and repository description, then compare their current game links with the URL given in the issue. Update both references so they point to https://githubschool.github.io/github-games-SallyNashed/; the task is done when each location uses that URL.
