[Request] Show used Zod version

[pablo-olmedo-poex]

Hi @nereumelo!

First of all, thank you so much for such an interesting project. I use it every day ❤️

I've noticed that certain methods are not available and this is because Zod has been updated since the last Zod Sanbox release.

It would be great to see which version of Zod is being used. Maybe even a version selector to test how a given schema behaves with different Zod versions.

Thanks in advance!
