Update to rodio 0.18 (#13612)

# Objective

- Adopted from #13528.
- `rodio` released 0.18! While we are working on migrating away from it
and towards `kira`, it is still good to keep our dependencies
up-to-date.

## Solution

- Update `Cargo.toml` to depend on `rodio` 0.18.
- #13528 was failing because it didn't update `rodio` for
`wasm32-unknown-unknown` too.

## Testing

- The CI should catch any errors here, but you can also run an audio
example if you want like `spatial_audio_2d`.

---

## Changelog

- Updated `rodio` to 0.18.
