Adding some useful resources in Git and Github Workshop guide.
Recently @xypnox and @sahil-shubham shared some nice git guides for beginners. We can share such useful things with the audience after the workshop and also they will be useful while preparing content.
The Git and Github doc has already been accepted. This PR just appends a list of useful resources. Hence I am merging it myself to avoid delay and reduce the effort for others.
