Assets from relative paths outside the asset folder not loading

[DGriffin91]

Bevy version 0.17.3

Tested on Arch Linux

Works in 0.17.2 but not in 0.17.3. Likely from this PR: #21643

This has the flight helmet gLTF in both:
temp/asset_load_test/assets/FlightHelmet/FlightHelmet.gltf
and
temp/FlightHelmet/FlightHelmet.gltf

Both load and are seen on screen in 0.17.2, but only the left one in 0.17.3.

0.17.3 error:
ERROR bevy_asset::server: Failed to load asset '../../FlightHelmet/FlightHelmet.gltf' with asset loader 'bevy_gltf::loader::GltfLoader': failed to read bytes from an asset path: Path not found: /temp/asset_load_test/assets/FlightHelmet/FlightHelmet.bin
