No return value for the Add nodes for Map/Set variables

Add nodes for variables using the container type Set/Map do not have a return values that states if an element was successfully added. The tool tip states that this should be the case. This return value was also present in previous versions of the engine (available in 4.17.2-3658906)

1. Open the editor
2. Open the level blueprint
3. Create a new variable
4. Make the variable an actor reference
5. Set the variable to the container type "Map"
6. Add a get of the variable to the graph
7. Pull off of the get variable and create an Add node

Result: The Add node does not have a return value (boolean)
Expected the Add node would have a return value (boolean) that states if an element was successfully added.
