Unable to set the custom icons

# Bug Report

## Problem

### What is expected to happen?
I want to customize the app icon, avoiding to use the default electron one.

### What does actually happen?
Building the app, it says "default Electron icon is used reason=application icon is not set" and it uses the default icons and not the ones I've specified in config.xml file.

## Information

### Command or Code

Config.xml file:
```xml






```
Command:
`cordova build electron`
Note: using cordova run electron --nobuild works, but it's not what i want :)

Build.json:
```json
{
"electron": {
"release": {
"windows": {
"package": [
"msi",
"appx"
],
"arch": [
"x64"
],
"signing": {
"release": {
"certificateFile": "",
"certificatePassword": ""
}
}
}
},
"debug": {
"windows": {
"package": [
"msi","zip"
],
"arch": [
"x64"
],
"signing": {
"release": {
"certificateFile": "",
"certificatePassword": ""
}
}
}
}
}
}
```

### Environment, Platform, Device, Version information

I'm on windows 11.
Cordova: 11.1.0
Cordova-electron: 3.1.0

## Checklist

- [x] I searched for existing GitHub issues

Start by reproducing the issue with cordova build electron using the supplied config.xml, build.json, and Windows environment. Trace how the build command reads the app and installer icon preferences; done means the generated app and installers use the configured icons instead of the default Electron icon.
