Remove the misleading word "updates" from system options (#23069)

Remove the misleading word "update" from system options

The second option in the system options dialog for integrations uses the word "updates" in both the headline and the explanation.

This is highly misleading as it sounds like polling for firmware updates for many device integrations.

Therefore the words "(state) changes" should be used instead.
