`bevy_utils::prelude` is the only module making the `DebugName` public

I noticed that bevy_utils::prelude makes DebugName available. But the debug_info module it is contained is private so one is forced to use prelude.

This is unusual as prelude is for a quick import that can be replaced with the "actual" location if desired.

I was about to write a PR, but the default mod is just one function (default()) which is exposed here.
So you can use bevy::utils::default directly without using bevy_utils::prelude::default. I'm not sure what the use case for bringing in "bevy_utils::default::*" would be other than using the one function contained in it. Could you elaborate on your problem?

use bevy::utils::default;

#[derive(Default)]
struct Foo {
    a: u32,
    b: u32,
}

fn main() {
    let _foo = Foo {
       a: 10,
       ..default()
    };
}

@Arne-Berner You are right, I mixed things up a bit. It is actually DebugName that is only reachable from prelude.

Crate authors often do not use the bevy crate but subcrates so it matters that it works from the bevy_utils crate. This way crates compile earlier (they do not have to wait for bevy + all its subcrates to compile) and users may not even use bevy if they do not need the full App.
