Add table of contents section to the readme file

[tatheer-fathima]

What's wrong with the existing documentation

Currently, the readme files doesn't have table of contents section which enhances the readability and easier navigation.

@andoriyaprashant I would like to work on it.
Please assign it to me under gssoc-ext and hacktoberfest.
