ts fixes (#992)

<!-- ELLIPSIS_HIDDEN -->



> [!IMPORTANT]
> Add `BamlLogEvent` support and update callback types to allow
`undefined` in TypeScript, JavaScript, and Rust files.
> 
>   - **Exports**:
> - Add `BamlLogEvent` to exports in `index.d.ts`, `index.js`, and
`typescript_src/index.ts`.
>   - **TypeScript Definitions**:
> - Update `streamFunction` and `streamFunctionSync` in `native.d.ts` to
allow `cb` parameter to be `undefined`.
>   - **JavaScript**:
> - Replace `console.error` with `loadErrors.push` in `native.js` for
error handling.
>   - **Rust**:
> - Update `stream_function` and `stream_function_sync` in `runtime.rs`
to allow `cb` parameter to be `undefined`.
>   - **Dependencies**:
> - Update `@napi-rs/cli` version in `package.json` from
`3.0.0-alpha.56` to `3.0.0-alpha.62`.
