type error when set basePath to OpenAPIHono

[sor4chi]

This will be ok

const app = new OpenAPIHono()
app.openapi(route, (c) => c.jsonT({ message: 'Hello' }))

But this will be error

const app = new OpenAPIHono().basePath("/hoge")
app.openapi(route, (c) => c.jsonT({ message: 'Hello' }))

this won't be type error, but basePath doesn't work

const app = new OpenAPIHono()
app.basePath("/hoge")
app.openapi(route, (c) => c.jsonT({ message: 'Hello' }))

All Example Code

import { OpenAPIHono, createRoute } from "@hono/zod-openapi";

const route = createRoute({
  method: 'get',
  path: '/message',
  responses: {
    200: {
      description: 'Get message',
    },
  },
})

const app = new OpenAPIHono()
app.basePath('/api')

app.openapi(route, (c) => c.jsonT({ message: 'Hello' }))

export default app;

Actually, I want to extend Hono's Context like (c.webSocket, c.storage, etc...) in hono-do. But this project includes basePath internally.
I found the same approach in OpenAPIHono so I throw this issue.
