feat(bevy_gltf_components): added support for the new 'nested' bevy_components hashmap from

the bevy_components add-on ! this means support for full component paths is working
 * no more need for short_names in that case: long names work !
 * support for short names for other components (for simplicity & compatibility) is still in but cleaned up
