Due to instability in the Rust WASM ecosystem, the trunk build
tool enforces that the Cargo-dependency version of `wasm-bindgen`
MUST match the version of the CLI supplied in the environment.
This can get out of sync when nixpkgs is updated. To resolve it,
wasm-bindgen must be bumped in the Cargo.toml file and cargo needs
to be run to resolve the dependencies.
Versions of `wasm-bindgen` in Cargo.toml:
Expected: '= ${pkgs.wasm-bindgen-cli.version}'
Actual: '${cargoToml.dependencies.wasm-bindgen}'
