`pccm` example is missing or not loading assets on bevy.org

fails to load assets and thus displays a mostly-blank scene.

It attempts to load , which does not exist, but (unlike the assets of another example I checked), does not then go on to try to load which does exist.

I don’t know enough about Bevy asset loading to say whether this is a problem with the example, Bevy, or the web site configuration, but `cargo run --example pccm --features="free_camera https bevy_feathers"` works, so it’s not the example being entirely broken.

Reproduce the failure at https://bevy.org/examples/3d-rendering/pccm/ and compare its asset-loading behavior with another working example. Trace how the website handles the missing outer_cube.glb.meta file, then verify that the pccm scene loads its assets and is no longer mostly blank.
