Update support extruder settings behavior

Changed the settings in RecommendedSupportSelector.qml so that now all extruders will not be updated by default. However, when a user changes the selected index, a temporary update to all extruders will be triggered. This allows for specific user-directed changes to propagate correctly across all extruders.
