Bug: Error in The Playground Toast Container transition property.

**Do you want to request a *feature* or report a *bug*?**

I would like to report a bug in The Playground Toast Container.

**What is the current behavior?**

-Current Code Snippet throws error.

**The issue can be resolved in 2 ways:**

1) Firstly we must import a library

`import { Bounce } from 'react-toastify';`

and replace `transition: Bounce,` with `transition={Bounce}`

2) Second way a much simpler way

just replace `transition: Bounce,` with `transition="Bounce"` on need to import any library.
