`SuccessResponseJSON` and `ErrorResponseJSON` always return `never`

[piousdeer]

Description

I think SuccessResponseJSON and ErrorResponseJSON weren't updated along with their non-JSON counterparts in v7 and they should've been something like this:

- export type JSONLike<T> = FilterKeys<T, `${string}/json`>;
+ export type JSONLike = `${string}/json`;

- export type SuccessResponseJSON<PathMethod> = JSONLike<SuccessResponse<ResponseObjectMap<PathMethod>>>;
+ export type SuccessResponseJSON<PathMethod> = SuccessResponse<ResponseObjectMap<PathMethod>, JSONLike>;

Name	Version
openapi-typescript	7.1.0
Node.js	v21.7.2
OS + version	NixOS

Reproduction

import type { SuccessResponseJSON } from "openapi-typescript-helpers";

type x = SuccessResponseJSON<paths["/a/valid/path"]["get"]>; // `never`

type y = SuccessResponse<ResponseObjectMap<paths["/a/valid/path"]["get"]>>; // works
