Bounce is not defined in documentation example — missing import causes runtime error.

I noticed that in the official documentation and Playground examples, the ToastContainer is shown using:
< ToastContainer transition={Bounce} />

However, the required import for Bounce is missing:
"**import { Bounce } from 'react-toastify';** "
This line is not shown

This causes a runtime error:
"_Uncaught ReferenceError: Bounce is not defined_"

Suggestion: Please add the missing import line to the docs:
**import { Bounce } from 'react-toastify';**
This would save many developers (especially beginners) from getting stuck on what seems like a syntax or runtime bug.

Thanks again! I’d be happy to open a pull request if needed.

Start with the official documentation and Playground examples that render ToastContainer with transition={Bounce}. Check the example imports and add the missing Bounce import where needed; done means the examples no longer raise “Bounce is not defined” at runtime.
