Move updateService.initialize into the update service awaiting LifecyclePhase.AfterWindowOpen

Lines 1197 to 1201 in 1995346

	// Initialize update service
	const updateService = accessor.get(IUpdateService);
	if (updateService instanceof Win32UpdateService || updateService instanceof LinuxUpdateService || updateService instanceof DarwinUpdateService) {
	await updateService.initialize();
	}

I suggest to either remove the await that was introduced 2 months ago or better listen to the LifecycleMainPhase.AfterWindowOpen and move this code into the update service.

As discussed, maybe product.target would be a way out, since we already encode this information in the product.
