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-DelphiDesigner

Start by opening README and the repository description settings, then locate the two URLs that still point to githubschool's copy. Update both to https://githubschool.github.io/github-games-DelphiDesigner; the work is done when the README link and repository description link point to that URL.
