The /docs/marketing/localized_description contains translations of the app description that is used in the PlayStore.

But this doesn't work for the F-Droid and it remains untranslated https://f-droid.org/de/packages/com.ichi2.anki/
The F-Droid expects that translations will be located in the /fastlane/metadata/android folder. During a new app release it will take automatically this descriptions.
So could you please move the the files under correct location? Or will you accept a PR for this.

The Crowdin has the /14-marketdescription.txt so it also should be moved there.
