Fix wrong method call in relationship replacement command (#18824)

Browse Source 
Fixes a small mix-up from #18058, which added bulk relationship
replacement methods.

`EntityCommands::replace_related_with_difference` calls
`EntityWorldMut::replace_children_with_difference` instead of
`EntityWorldMut::replace_related_with_difference`, which means it always
operates on the `ChildOf` relationship instead of the `R: Relationship`
generic it's provided.

`EntityCommands::replace_children_with_difference` takes an `R:
Relationship` generic that it shouldn't, but it accidentally works
correctly on `main` because it calls the above method.
