[docs] Fix incorrect clone URL in README installation steps

[gaurikhairnar-live]

Description:
The installation section under "Quick Start" shows a git clone command pointing to https://github.com/gollabharath/gamify.git which is an old/wrong repository. New contributors who copy-paste this command will either get an error or clone the wrong repo. It should be updated to https://github.com/DeadIndian/Gamify.git.What is required: Simply update the clone URL in the README to match the correct repository.
Level: 🟢 Beginner
