Expected behavior

When including the following code in forge.config.ts, I expected to only see a folder called resources in process.resourcesPath.

packagerConfig: {
    extraResource: ['./resources'],
  },

Actual behavior

Instead, there is also a folder called app that contains the entire local repository, making the final package almost 1GB. Without extraResource, the app folder does not show up in process.resourcesPath.

Steps to reproduce

Add a folder in a top level directory, add that folder as an extraResource, then run electron-forge make.
