Wrong syntax for output of non-C++ deprecation lists for enum members

[StefanBattmer]

Describe the bug
When e.g. building a C# or Python documentation the namespace syntax for enum members marked as being deprecated will show up using C++ style namespace syntax in the deprecation list

Expected behavior
Instead of Bla::blub::myEnum I would like to see Bla.blub.myEnum
