Sandcastle examples fail to load data

## What happened?

Two of the gallery Sandcastles appear to be broken:

- "Web Map Service" reports CORS errors and does not load the relevant data.
- "I3S Feature Picking" throws runtime errors when you click on a building:
```
RuntimeError: Failed to load binary: https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/NYC_Attributed_v17/SceneServer/layers/0/nodes/1744/attributes/f_15/0?f=pjson
```

## Reproduction steps

### Web Map Service

1. Load the [Web Map Service sandcastle](https://sandcastle.cesium.com/?id=web-map-service-wms)
2. Observe the errors in the Sandcastle. The data visible in the Sandcastle thumbnail never appears in the scene.

### I3S Feature Picking

1. Load the [I3S Feature Picking sandcastle](https://sandcastle.cesium.com/?id=i3s-feature-picking)
2. Zoom in
3. Wait for buildings to load
4. Click on a building
5. Observe errors in the console
