add github profile pic,rank user github id and the gssoc leaderboard link in the certificate

@sanjay-kv i think we can add these 2 also in the certificate

Lets say someone wants to confirm that we were actually in the top 100 or 50 or something they can just click on the leaderboard and verify it quickly i think there are many people who are going to put this achievement in their resume or upload it somewhere when they are asked for achievement certificate

It should be good to add the rank and the gssoc leaderboard link so that when a person is checking your certificate they can see that okay this person had got this rank then they can just go to the leaderboard and check that if the person had actually reached that rank

The github profile image i am not sure but i think that can also be a good addition to the certificate as there are many certificates like that of nptel where they include a photo of the candidate
