Fix CI for Rust 1.72 (bevyengine#9562)

[Rust 1.72.0](https://blog.rust-lang.org/2023/08/24/Rust-1.72.0.html) is
now stable.

- `let-else` formatting has arrived!
- I chose to allow `explicit_iter_loop` due to
rust-lang/rust-clippy#11074.

We didn't hit any of the false positives that prevent compilation, but
fixing this did produce a lot of the "symbol soup" mentioned, e.g. `for
image in &mut *image_events {`.

  Happy to undo this if there's consensus the other way.
