Change the MapLibre URL to point to the new example

[safwat-halaby]

Hello,

I'd like to notify the 3d-tiles-renderer maintainers of the newly created maplibre-gl-three. It is a thin wrapper that glues 3d-tiles-renderer, Three.js, and MapLibre in a way that is cleaner than the current official MapLibre example.

It will replace and improve upon the existing example in maplibre-gl-js pull request #8567. Check out the PR for more info.

After Maplibre's 8567 is accepted, the link to the MapLibre guide in this repo's readme will break. This PR points to the new link and it should be merged only after #8567 goes live.

As expected, the old example is now a 404:

https://maplibre.org/maplibre-gl-js/docs/examples/add-3d-tiles-using-threejs/

The two new examples are now live:

• https://maplibre.org/maplibre-gl-js/docs/examples/add-3d-tiles-3d-objects-and-models-using-threejs/
• https://maplibre.org/maplibre-gl-js/docs/examples/raycast-3d-tiles-using-threejs/

It's time to merge this PR.
