Add geek jokes to file

[sameerkumar18]

I think the API needs more jokes. Currently, there are around 500 or so. You can add geek jokes in the .json file.

(Do add the reference to the source in description of the pull request, if you're taking the content(joke) from somewhere else)

I am new to GitHub. But very creative to make jokes. How can I contribute my jokes to your project? Please help me.

@NehaRay21 fork this repo, go to this repo, which shows forked up, in your profile, go to the destination directory, open the .json file, edit it by adding new key:entry objects of jokes, then save it. Voila!
