order_by field not working in /api/worlds

The `order_by` field in `https://places.decentraland.org/api/worlds` is not working as expected.

- When listing worlds, the values `updated_at`, `most_active`, and `like_score` for `order_by` do not work.
- The endpoint returns the same results regardless of which value is passed, even with a random value or if the `order_by` parameter is omitted.

**Expected behavior:**
The results should be properly ordered according to the specified `order_by` value.
