### Electron Forge version

6.2.1

### Electron version

24.1.2

### Operating system

Windows 11

### Last known working Electron Forge version

_No response_

### Expected behavior

Have this line defined on the .webpack/main bundle:

`if (typeof __webpack_require__ !== 'undefined') __webpack_require__.ab = __dirname + "/native_modules/";`

### Actual behavior

This line
`if (typeof __webpack_require__ !== 'undefined') __webpack_require__.ab = __dirname + "/native_modules/";`
is completely missing from the webpack main process bundle

### Steps to reproduce
- Create a new project with the webpack template
- Use a native node module in windows and run `npm start`

### Additional information

Very similar to this issue https://github.com/electron/forge/issues/3183. It would be a bummer to have to switch to something different from electron-forge
