Add Social Badges In docs/README.md

[thealphadollar]

We want to add at least the following badges (see root README.md) to the docs/README.md file:

• Follow
• Star
• Watchers

We are currently using shields.io and the same code as present in README.md can be used. However, a caveat is that the same needs to be added using the Python code (

GSoCOrgFrequency/src/utils.py

Line 86 in 4ed009f

f.writelines("The following table contains the organisations that have been part of Google Summer of Code at least once from 2009 to {} - number of times they have participated, technologies they use, topics they work on, GSoC category, and the latest GSoC year they participated in.\n\nMore information and year-wise data available at [thealphadollar/GSoCOrgFrequency](https://github.com/thealphadollar/GSoCOrgFrequency).\n\n".format(year))

) instead of manually adding it. This way we will not lose the same as we update the docs.
