Why is AppUpdater its own class?

[aolsenjazz]

Summary

autoUpdater configuration is done inside of its own class in main.ts. I haven't seen anything in electron-updater docs that suggest this pattern is necessary or normal:

class AppUpdater {
  constructor() {
    log.transports.file.level = 'info';
    autoUpdater.logger = log;
    autoUpdater.checkForUpdatesAndNotify();
  }
}

Happy to be wrong here, but the actual autoUpdater configuration ought to be moved to where new AppUpdater() is, or put inside of it's own function block. Will open a PR to do this - lmk.
