feat: playground

[Rohan-Nair]

Description

Added a new route named playground so that users can try out all the features provided by diffs in one place without having to locally set up anything.

Motivation & Context

It's pretty handy and useful to have the features provided by diffs on the web so anyone even wanting to compare text can use it.

Hey @Rohan-Nair, I had a branch to do something similar that I never pushed to a PR. I just opened that and will review both our branches to see what makes most sense to continue with. Thanks in advance!
