Clarify Bengali localization contribution path and inactive Transifex link

Context

I would like to contribute Bengali (Bangla, bn) localization and proofreading for the Navigation SDK for Android.

The current contribution guide directs translators to:

https://www.transifex.com/mapbox/mapbox-navigation-sdk-for-android/

However, that URL currently returns a 404 page. I also could not find values-bn resources in the current main branch.

At the same time, the current Navigation SDK localization documentation lists Bengali as supported for user-interface elements:

https://docs.mapbox.com/android/navigation/guides/localization/

Questions

1. Is Bengali UI localization currently distributed from a source outside this repository?
2. What is the current translation platform or project URL for contributing Bengali translations?
3. If Bengali translations need to be restored or updated, would the maintainers welcome a Bengali translation/proofreading contribution?
4. Should new translations target all resources listed in .tx/config, or is there a newer localization workflow?

I am a native Bengali speaker from Bangladesh and would be happy to translate and review the navigation terminology carefully once the supported contribution workflow is confirmed.

Beginne mit dem Contribution Guide und .tx/config und vergleiche sie anschließend mit dem im Bericht verlinkten Localization Guide. Bestätige den unterstützten Bengali-Workflow und die Übersetzungs-URL mit den Maintainers; abgeschlossen ist die Aufgabe, wenn der Leitfaden und der Link einen abgestimmten aktuellen Pfad und den Status von Bengali beschreiben.
