Context
In order to make class Language more narrow, functions related to namespace formatting should be extracted to NamespaceNameLocalizer in T252137. As next step, relevant functions from Language should be proxified to the newly created class and soft deprecated.
Expected Results
- methods getNamespaces, getFormattedNamespaces, getNsText, getFormattedNsText, getGenderNsText, getLocalNsIndex, getNamespaceIds etc should be proxied to NamespaceNameLocalizer.
