Testbed for 3d (#15993)
# Objective - Progress towards #15918 - Add tests for 3d ## Solution - Add tests that cover lights, bloom, gltf and animation - Removed examples `contributors` and `load_gltf` as they don't contribute additional checks to CI ## Testing - `CI_TESTING_CONFIG=.github/example-run/testbed_3d.ron cargo run --example testbed_3d --features "bevy_ci_testing"`
