Could not find package openstream/mage2-locale-de-ch

[nickw108]

I adapted this from splendid/de_de, but get the following error when running composer require openstream/mage2-locale-de-ch

[InvalidArgumentException]                                                                                                                       
  Could not find package openstream/de_ch at any version for your minimum-stability (alpha). Check the package spelling or your minimum-stability

Where do I have to add the new namespace?

Changed namespace on packagist.org.
