qwik: api/dinosaurs routes defined but not called from anywhere

Seems data is not loaded from backend api, it loaded from json file directly.

For example:

https://github.com/denoland/examples/blob/main/with-qwik/src/routes/index.tsx:

import data from "~/data/dinosaurs.json" with { type: "json" };

export const useDinosaurs = routeLoader$(() => {
  return data;
});
