Implement push to github

[gautamkrishnar]

Is your feature request related to a problem? Please describe. It will reduce the no of steps required to publish the readme

Describe the solution you'd like After generating the readme, there will be a push to github button. By clicking on that button, user will be prompted to enter his PAT and the repo url. Pushing and cloning will be done entirely in the browser, no backend server is required.

Describe alternatives you've considered None

Additional context I will be using github api for the same

I will work on this for this year's Hacktoberfest.
