Type of nullable is not set to option.Option

[fridewald]

A nullable field should result in an option.Option type

Given this typedef:

{
  "properties": {
    "page": { "nullable": true, "type": "string" }
  }
}

the library produces

import decode
import gleam/json
import gleam/option

pub type Data {
  Data(
    page: String,
  )
}

pub fn data_decoder() -> decode.Decoder(Data) {
  decode.into({
    use page <- decode.parameter
    Data(page:)
  })
  |> decode.field("page", decode.nullable(decode.string))
}

pub fn data_to_json(data: Data) -> json.Json {
  json.object([
    #("page", json.nullable(data.page, json.string)),
  ])
}

Also, decode.nullable should be decode.optional
