Description

In my schema, I've specified that the only response code is 201. However, if I write my handler as returning a 200, I don't get a type error:

Steps to Reproduce

import { FastifyPluginAsyncJsonSchemaToTs } from "@fastify/type-provider-json-schema-to-ts"

const plugin: FastifyPluginAsyncJsonSchemaToTs = async function (
    fastify,
    _opts
) {
    fastify.post(
        "/sign-up",
        {
            schema: {
                response: {
                    201: {
                        type: "object",
                        properties: {
                            email: { type: "string" },
                        },
                        required: ["email"],
                    },
                },
            },
        },
        async (_, reply) => {
            return reply.status(200).send() // This should show a type error on status 200 because not in schema
        }
    )
}

export default plugin

Expected Behavior

When using generics, it'll show a type error on 200 which I believe is the desired behaviour.
