language_mapping doesn't work for %locale% placeholder

Describe the bug I’m trying to set up Google Play’s changelogs translation. In most cases, Google prefer the full dashed locale code (e.g. en-US), but in some cases, they require the two-letter code (th, lv, fil). I have the next configuration:

files:
  - source: /fastlane/metadata/android/en-US/changelogs/default.txt
    dest: /android/default-changelog.txt
    translation: /fastlane/metadata/android/%locale%/changelogs/default.txt
    languages_mapping:
      locale:
        th-TH: th

But it doesn’t do anything.

To Reproduce Steps to reproduce the behavior:

1. Configuration file: above
2. Execute CLI command: crowdin download
3. See that translations are still downloaded to the th-TH folder rather than th, defined in the languages_mapping setting.

Expected behavior All locales should be stored in their %locale% folders, but th-TH should be mapped to the th directory.

Environment:

• OS: MacOS
• Version: 10.14.6
• CLI: 3.1.15

Hi @erickskrauch @Wohlie ! We have updated the Language Mapping feature description in the documentation.

@andrii-bodnar, thanks, that worked! It will be nice if the cli application will notify users about invalid mappings. Also, it will be good, if the documentation will better describe this feature.
