Fix validation errors in Fox.glb

[rparrett]

Objective

Fix gltf validation errors in Fox.glb.

Inspired by #8099, but that issue doesn't appear to describe a real bug to fix, as far as I can tell.

Solution

Use the latest version of the Fox from glTF-Sample-Assets.

Testing

Dropped both versions in https://github.khronos.org/glTF-Validator/

cargo run --example animated_mesh seems to still look fine.

Before:

The asset contains errors.
"numErrors": 126,
"numWarnings": 4184,

After:

The asset is valid.
"numErrors": 0,
"numWarnings": 0,

Discussion

The 3d testbed was panicking with

thread 'main' panicked at examples/testbed/3d.rs:288:60:
called `Result::unwrap()` on an `Err` value: QueryDoesNotMatch(35v1 with components Transform, GlobalTransform, Visibility, InheritedVisibility, ViewVisibility, ChildOf, Children, Name)

Which is bizarre. I think this might be related to #17720, or maybe the structure of the gltf changed.

I fixed it by using updating the testbed to use a more robust method of finding the correct entity as is done in animated_mesh.

Cool!
nitpick: maybe refer to https://github.com/KhronosGroup/glTF-Sample-Assets/blob/main/Models/Fox/glTF-Binary/Fox.glb (in the future?) ; I think it's the same model but I was surprised to see "latest model" linking to an archived repo.

Oops, updated link and confirmed that it's the same.
