old releases in mangento repository

- Root composer.json requires magenerds/language-de_de ~1.0.21, it is satisfiable by magenerds/language-de_de[1.0.21, ..., 1.0.35] from composer repo (http://repo.packagist.org) but magenerds/language-de_de[1.0.0, 1.0.2] from composer repo (https://repo.magento.com) has higher repository priority. The packages with higher priority do not match your constraint and are therefore not installable. See https://getcomposer.org/repoprio for details and assistance.
