fix: Display multipicker on Created By source filter (#10543)

fix: #9674 

When the selected filter is Is and the field type is ACTOR, we now show
ObjectFilterDropdownSourceSelect instead of a text input. This ensures
proper selection for actor-based filters. Also previously, when a user
changed the selected option, all default values were getting wiped out
so i have made some changes in updatedSelectedItems
