_Show an error something like Unable to access the network_
_Tells that PowerToys is up-to-date even if network access is nonexistent_

we can show a error message if update check procedure is failed.
Maybe also change the text to the similar, but more correct/safe "No updates found"?
Shipped with 0.27 release. https://github.com/microsoft/PowerToys/releases/tag/v0.27.0
