Documentation for derive macros is in the wrong place

## How can Bevy's documentation be improved?

For derivable traits such as `WorldQuery`, `SystemParam`, `Bundle`, etc., documentation for the derive macro is placed on the [trait definition](https://github.com/bevyengine/bevy/blob/6b75589e2c91429eb6c35574840d47d39b2379b9/crates/bevy_ecs/src/query/fetch.rs#L46) itself, rather than the derive macro. This means that when hovering over a `#[derive(WorldQuery)]` attribute, it appears to be [mostly undocumented](https://github.com/bevyengine/bevy/blob/6b75589e2c91429eb6c35574840d47d39b2379b9/crates/bevy_ecs/macros/src/lib.rs#L403).

Any documentation regarding the derive macro should be moved *to* the derive macro -- this information is not relevant to consumers of the trait, and is not discoverable for those trying to derive it.

Compare the derive-related documentation in crates/bevy_ecs/src/query/fetch.rs with the derive macro documentation in crates/bevy_ecs/macros/src/lib.rs, including WorldQuery, SystemParam, and Bundle. Move the macro-specific guidance so it appears on the derive macros and verify that trait documentation remains focused on the traits while hovering over each derive attribute shows the relevant information.
