Fix crash when clicking on "Interpolation Mode" with nonexistent node path

issue reference [https://github.com/godotengine/godot/issues/81769]

- adding a nullptr check on a Node pointer obtained from get_node(NodePath) in case it is null now we wont execute the next instruction

> ClassDB::get_property_info(nd->get_class(), prop, &prop_info);

Which then prevents the crash
