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-ramyasri06

Open the repository description settings and README, then find the existing game URLs. Update both references to https://githubschool.github.io/github-games-ramyasri06 and verify that the description and README now point to that URL.
