Form field types don't get inferred from zod schema

[pavle99]

Describe the bug

Without type casting the default values, the form type gets inferred as ReactFormExtendedApi<TYPE, Validator<unknown, z.ZodType<any, z.ZodTypeDef, any>>> where TYPE is the type of object passed to default values instead of it being the type inferred from the zod schema.

Your minimal, reproducible example

https://stackblitz.com/edit/tanstack-form-9w9uhn8b?file=src%2Findex.tsx

Steps to reproduce

Try removing the as User in line 35 in index.tsx file and see how the type of the form changes when you add/remove/modify any of the fields in the default values.

Expected behavior

Expected the form type to be inferred from the zod schema passed, as well as have type safety in default values without needing to manually cast the type.
