Wrong version returned from app.getVersion()

## Prerequisites

- [x] Using npm
- [x] Using an up-to-date [`main` branch](https://github.com/electron-react-boilerplate/electron-react-boilerplate/tree/main)
- [x] Using latest version of devtools. [Check the docs for how to update](https://electron-react-boilerplate.js.org/docs/dev-tools/)
- [ ] Tried solutions mentioned in [#400](https://github.com/electron-react-boilerplate/electron-react-boilerplate/issues/400)
- [ ] For issue in production release, add devtools output of `DEBUG_PROD=true npm run build && npm start`

## Expected Behavior

The correct app version is returned for both envs: production and development.

## Current Behavior

In the production `app.getVersion()` returns the correct app version.
In the development it returns Electron's version (ss below)

## Steps to Reproduce

In `main.ts` (L:28) file replace:
```ts
ipcMain.on('ipc-example', async (event, arg) => {
const msgTemplate = (pingPong: string) => `IPC test: ${pingPong}`;
console.log(msgTemplate(arg));
event.reply('ipc-example', 'pong'));
});
```
with
```ts
ipcMain.on('ipc-example', async (event, arg) => {
const msgTemplate = (pingPong: string) => `IPC test: ${pingPong}`;
console.log(msgTemplate(arg));
event.reply('ipc-example', msgTemplate(`pong, version: ${app.getVersion()}`));
});
```

## Possible Solution (Not obligatory)

1. I know that one of the possible solutions is to insert the version in root package.json but IMO we shouldn't take care and remember about that we should change the version in both package.json files.

2. Merge root and release/app package.json files

It would be nice to have one source of truth for version number on both environments.
