Fixes bevyengine/bevy#8898 (comment):

Screenshot 2023-06-24 at 23-42-53 any_with_component in bevy_ecs schedule common_conditions - Rust

It now prints as shown below (which conforms to the style guide):

pub fn any_with_component<T: Component>(
) -> impl FnMut(Query<'_, '_, (), With<T>>) -> bool + Clone

The bug was introduced in #109011.

Using @snapshot instead of @has since I couldn't figure out if it was possible to test for the presence of line breaks with it (I love the Htmldocck DSL ^^).
