Resolve cpu spikes when options dialog is shown

Disable auto-update of the advanced settings tree widget. This is causing CPU spikes every 2 seconds while the dialog is open. It's useless for QGIS, because this dialog is modal and blocking, and changes to settings aren't saved until the dialog is dismissed. So basically nothing should be updating these settings while the dialog is opened anyway... Fixes #32892 (cherry picked from commit 3b29dba)
