Change World::inspect_entity to return an Iterator instead of Vec (#13934)

Browse source 
# Objective

Fixes #13933.

## Solution

Changed the return type.

## Testing

Fixed and reused the pre-existing tests for `inspect_entity`.

---

## Migration Guide

- `World::inspect_entity` now returns an `Iterator` instead of a `Vec`.
If you need a `Vec`, immediately collect the iterator:
`world.inspect_entity(entity).collect<Vec<_>>()`
