chore: crowdin.yml make Fastlane metadata translatable

To make the app description translatable the files inside of the `fastlane` directory needs to be added in Crowdin. During the next release the F-Droid will peak the new translations. BTW other apps use `%android_code%` for the `values-*` like here: ```yaml files: - source: /app/src/main/res/values/strings.xml translation: /app/src/main/res/values-%android_code%/%original_file_name% - source: /app/src/main/res/raw/orgzly_getting_started.org translation: /app/src/main/res/raw-%android_code%/%original_file_name% ```
