Subject: [PATCH] tracing: fix `wasm_bindgen_test` macros (#2675)

## Motivation

Tests involving `wasm_bindgen_test` currently fail:

https://github.com/tokio-rs/tracing/actions/runs/5756318807/job/15605512576

## Solution

- [x] Use `extern crate wasm_bindgen_test` to side-step `no_implicit_prelude`.
- [x] https://github.com/rustwasm/wasm-bindgen/pull/3549
- [ ] Consume the release `wasm_bindgen_test` containing said change.
