Broken Playground Link in Baked Texture Animations Documentation

[ertugrulcetin]

The Playground link in the Baked Texture Animations documentation appears to be broken:

PG: https://playground.babylonjs.com/#3NIXCL#707

The Playground cannot be opened because the referenced models return a 404 Not Found error.

Here is the working demo after updating the assets - https://playground.babylonjs.com/#3NIXCL#737

I will update the docs later as well, of course
