Fixed docs for derive(WorldQuery). (#5283)

For `derive(WorldQuery)`, there are three structs generated, `Item`, `Fetch` and `State`. 
These inherit the visibility of the derived structure, thus `#![warn(missing_docs)]` would
warn about missing documentation for these structures.

- [ ] I'd like some advice on what to write here, as I personally don't really understand `Fetch` nor `State`.
