Document issue with GitHub Actions hanging

### Pre-flight checklist

- [X] I have read the [contribution documentation](https://github.com/electron/forge/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [code of conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project uses.
- [X] I have searched the issue tracker for a bug that matches the one I want to file, without success.

### Electron Forge version

6.4.1

### Electron version

25.0.1

### Operating system

macOS 12.6.7

### Last known working Electron Forge version

N/A

### Expected behavior

`electron-forge make` should succeed and publish the distributable to `out/`. Instead, it is hanging after the `[STARTED] Making a pkg distributable for darwin/x64` step.

### Actual behavior

yarn make hangs in the github action

### Steps to reproduce

Running `electron-forge make` in a Github action.

### Additional information

## Overview:
* `electron-forge make` succeeds when I run it for my package locally (personal mac M1). The distributable is built and saved successfully.
* Github logs for the action stop here (will run for 1hr+ without doing anything):
```
[SUCCESS] Running postPackage hook
[SUCCESS] Running package command
[STARTED] Running preMake hook
[SUCCESS] Running preMake hook
[STARTED] Making distributables

* I also tried building for `arm64` with the same result, using `yarn make --arch arm64`
