Optional. Get supported languages of this model.

The format depends on model type:

- AutoML Translation models:
  `projects/{project-number-or-id}/locations/{location-id}/models/{model-id}`

- General (built-in) models:
  `projects/{project-number-or-id}/locations/{location-id}/models/general/nmt`,


Returns languages supported by the specified model.
If missing, we get supported languages of Google general NMT model.
