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-joelaltice/

Update the repository description and README so both URLs point to https://githubschool.github.io/github-games-joelaltice/. Start by checking the current link in the README and the repository metadata, then verify that both links resolve to this game copy.
