Depend on wasm-bindgen 0.2.89 or higher

wasm-bindgen 0.2.83 is not compatible for a wasm ABI change that
rustc wishes to enable by default for wasm, currently gated behind
passing the -Zwasm-c-abi flag to rustc.

wasm-bindgen 0.2.89 should exhibit seamless behavior before and
after the ABI change matches the C ABI, so depend on that.
