feat(zod-validator): support coerce

[yusukebe]

Fixes #368

Now you can use coerce.

const app = new Hono()

const schema = z.object({
  page: z.coerce.number(),
})

const route = app.get('/page', zValidator('query', schema), (c) => {
  const { page } = c.req.valid('query') // pages is `number`
  return c.json({ page })
})

const client = hc<typeof route>('/')
const res = await client.page.$get({
  query: {
    page: '123', // you should pass `string`
  },
})

const { page } = await res.json() // page is `number`
