Add a zod.dev/playground

[IchordeDionysos]

There should be a playground for testing out zod schema right in the documentation without having to run code to check if the schema is working as intended.

This would make it much more straightforward to validate the schema or test different behaviors of the schema.

Just like the Joi sandbox: https://joi.dev/tester/
