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-Radhikamuvva/

Inspect the repository description and README for the existing game URL. Update both references to https://githubschool.github.io/github-games-Radhikamuvva/; the work is done when neither location points to githubschool's copy.
