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-Shegox

Update the repository description and the README so both URLs point to https://githubschool.github.io/github-games-Shegox rather than GitHub School's copy. Check the repository description and README after editing to confirm both links use the requested destination.
