Subject: [PATCH] Add `world` and `world_mut` methods to `RelatedSpawner`
 (#18880)

# Objective

`RelatedSpawnerCommands` offers methods to get the underlying
`Commands`.
`RelatedSpawner` does not expose the inner `World` reference so far.

I currently want to write extension traits for both of them but I need
to duplicate the whole API for the latter because I cannot get it's
`&mut World`.

## Solution

Add methods for immutable and mutable `World` access
