Add DisplayPreferencesDtoNullabilityFixHook

A hook that modifies the type of the "customPrefs" property in "DisplayPreferencesDto" to fix a nullability issue. In the 10.7 API specification the value of the map is incorrectly labelled as not-null. This hook changes the type to the exact type emitted from the 10.8 alpha API specification.
