Swagger creates invalid OpenAPI due to missing response descriptions

[mikkelam]

Example:

import Elysia from "elysia";
import { swagger } from "@elysiajs/swagger";

const app = new Elysia().use(swagger()).get("/", {}, {}).listen(3000);

with elysia 1.2.9 and swagger 1.2.0 produces this swagger (converted to yaml)

openapi: 3.0.3
info:
  title: Elysia Documentation
  description: Development documentation
  version: 0.0.0
paths:
  /:
    get:
      operationId: getIndex
      responses:
        '200': {}
components:
  schemas: {}

which produces errors in here: https://editor.swagger.io/

Structural error at paths./.get.responses.200
should have required property 'description'
missingProperty: description
Jump to line 10

Perhaps the plugin should just prefill some sample text like "Successful response" for 200 and so on (it seems like fastapi does that).

I could try and suggest some code changes if authors are happy with this approach
