Consider making response descriptions optional in openapi zod schema

[brettimus]

Code:

fpx/packages/types/src/openapi.ts

Line 36 in 07c4a09

description: z.string(),

@mies hit an issue with Hono-Zod-OpenAPI where we wouldn't show docs for a response because our zod schema rejected a response that didn't have a description along with it

Technically the current schema is in line with what OpenAPIHono expects - it will show a type error in your app if you don't provide a description for the response... however, it could be funky for end users to not see a Docs tab show up for their route.
