German translation for Switzerland for country Turkey differs from Germany

Overview

The country name / translation for the country turkey differs for locale 'de_CH' from locale 'de_AT' or 'de_DE'. Why? In my opinion we say Türkei as well.

Steps to Reproduce

>>> from babel import Locale
>>> _locale = Locale.parse('de_CH')
>>> _locale.territories.get('TR')
'Türkiye'
>>> _locale = Locale.parse('de_DE')
>>> _locale.territories.get('TR')
'Türkei'
>>> _locale = Locale.parse('de_AT')
>>> _locale.territories.get('TR')
'Türkei'
