gendoc: fix localization of help topic When a topic provides a callable method for its text, most likely this text will be generated from different parts, so it does not make sense to apply gettext on the whole result, rather the method should provide translation by itself. This is the case with the extensions topic, which triggers a double gettext call, making the ASCII codec fail when it encounters 8 bit characters, and prevents the documentation from being built.
