Reproduction

Describe the bug

If we change/add another field (bar) in the transform callback and then pick it - Nuxt will show us TS error (nuxi typecheck) but works correctly in runtime:

Type '"bar"' is not assignable to type '"id" | "foo"'.

Expected:

• correct types when use pick and transform together
• do not allow to use pick and transform together

I would expect that only pick or transform are used - not both. Perhaps we could document this, or update types to disallow.

@danielroe I've opened a PR to improve documentation about pick and transform. Hope will be useful!

@danielroe opened another PR since I've messed up things in the previous PR 🙄
