[Pack up] Prompt validations are not typed

[joshuaellis]

What version of @strapi/pack-up are you using?

• version: 5.0.0

What's Wrong?

When creating a custom template and using the definePackageOption function, the validate property function is not typed, because pack-up uses a version of prompts without types, you then have to install your own @types/prompts package

Expected Behaviour

You should not need to install the package and the types should be available. To solve this, move the types package to the dependences property of the package.json
