Node _dirname becomes undefined

Describe the bug:

The Electron project won't start because the Node variable __dirname becomes undefined once run through js-confuser.

Config and Small code sample

Config:

{
  target: "node",
  preset: "medium"
}

Code:

const mainWindowOptions = {
    width: 800,
    height: 600,
    icon: 'build/icon.png',
    webPreferences: {
        preload: path.join(__dirname, 'preload.js'),
        nodeIntegration: false,
        enableRemoteModule: false,
        contextIsolation: true,
        sandbox: true,
        autoHideMenuBar: true,
        webviewTag: true
    }
}

Expected behavior

The program should be able to create a path to a file based on the working directory.

Actual behavior

Program won't start:

App threw an error during load
TypeError: Cannot read properties of undefined (reading '__dirname')

Additional context

The internal node variable __dirname is no longer recognized.
