Use the new TranslationResult properties from ctranslate2

[pirhoo]

Hello,

I noticed a deprecation warning when running the FewShotTranslation.apply_packaged_translation method:

DeprecationWarning: Reading the TranslationResult object as a list of dictionaries is deprecated and will be removed in a futur version. Please use the object attributes as described in the documentation: https://opennmt.net/CTranslate2/python/ctranslate2.TranslationResult.html

This could lead to an exception:

> translated_tokens += translated_batch[i]["tokens"]                                                             
SystemError: <built-in method __getitem__ of PyCapsule object at 0x7d8642cd7d80> returned a result with an exception set 

So I simply used the new properties as suggested by ctranslate2.

Let me know if you want me to add a safer access to the properties for retro-compatibility.

Thanks for the great tool!

Hello 👋

Just wanted to check if you could review my PR ; Unfortunately this error is a bit blocking for me.

Good catch thank you!

I pushed this change in v1.9.5

[pirhoo]

Wonderful, thanks!

Why was this causing issues for you? This fix is definitely correct but I've never seen the deprecated version cause problems.

The error started to appear for me when upgraded Argos Translate from 1.7 to 1.9: ICIJ/es-translator@a2e329b

As you can see, CTranslate2 is a transitive dependency for me. No idea why the error did not appear sooner (I saw you upgraded it prior to Argos Translate 1.8), really weird!
