V3 Upgrade: An error occurred while parsing the WebWorker bundle

Nobody has claimed this yet.

**mapbox-gl-js version**: 3.8.0

**browser**: Chrome Version 130.0.6723.117

### Steps to Trigger Behavior

1. Upgrade to mapbox-gl v3
2. Run the application

### Link to Demonstration

https://jsbin.com/

Cannot easily provide a reproduction.

The application is a react app with webpack 4 and babel 8.

### Expected Behavior

It should render the map after following the V3 migration guide.

### Actual Behavior

An error occurred while parsing the WebWorker bundle


This happens when importing with

```js
import mapboxgl from 'mapbox-gl'
```

If i import with previous transpilation suggestion i get another error.

```js
import mapboxgl from '!mapbox-gl'
```

```
./node_modules/mapbox-gl/dist/mapbox-gl.js 34:21870
Module parse failed: Unexpected token (34:21870)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
```

Start by reproducing the issue in a React application using webpack 4 and Babel 8, testing both `import mapboxgl from 'mapbox-gl'` and the `!mapbox-gl` form. Compare the resulting WebWorker bundle parse errors with the V3 migration guide; done means the map renders without a bundle parsing error.
