[BUG] nextcloud-stats widget doesn't work

[stasmotorny]

Environment

Self-Hosted (Docker)

System

Linux

Version

3.1.1

Describe the problem

I got error Cannot read properties of undefined (reading 'app_updates') for nextcloud-stats widget.
Nextcloud serverinfo does not return app_updates anymore, to get this value you should add URL parameter skipApps=false.

Beginning with Nextcloud 28, the monitoring endpoint no longer provides information about available app updates, as
gathering the data always involves at least one external request to apps.nextcloud.com.
You can still ask the monitoring endpoint to show new app updates by using the URL parameter skipApps=false. However,
please do not check this endpoint too often.
