Artifact containers can safely store radioactive objects (version 2) (#19652)

* Artifact containers suppress the radioactive of artifacts inside them

* Updated to reflect changes to RobustToolbox

* Made necessary changes after updating RT

* Removed test code

* Made requested change

* Updated due to changes to RobustToolbox

* Renamed function

* Updated to accommodate changes to RobustToolbox

* Actually resolve merge conflict?

* Removed unnecessary change

* Made requested changes

* retrigger checks

* Retrigger checks
