Types: zValidator param validation makes input optional where it should be required

[MonsterDeveloper]

Reproduction:

1. Given the exact same schema with 1 required field, create 2 validators: one for param, the other one for json:

const schema = z.object({ id: z.string() })

const paramValidator = zValidator("param", schema)

const jsonValidator = zValidator("json", schema)

2. For the jsonValidator, the input type is inferred correctly: id is required
   

3. For the paramValidator, however, the id field in the input type is optional for an unknown reason, while it should be marked as required since the schema says it is not optional and not nullable:
   

This example is not working as expected, i.e. accepts undefined as a param:

Hi @MonsterDeveloper

Thank you for raising the issue. This is not only the Zod Validator issue. It is hono issue. I've transferred it as hono's issue.
