pipeline("translation", model="Helsinki-NLP/opus-mt-fr-en") raises KeyError

In (1.) Transformer models - chapter 3, the example code in translation part:
`translator = pipeline("translation", model="Helsinki-NLP/opus-mt-fr-en")` it gives **KeyError**: "Unknown task translation, available tasks are.... For Hugging Face transformers version 5.0+, the core translation pipeline is no longer included by default in the standard pipeline() registry.

Start in (1.) Transformer models, chapter 3, at the translation example containing pipeline("translation", model="Helsinki-NLP/opus-mt-fr-en"). Check the current Transformers pipeline documentation and reproduce the KeyError with the documented version context. Done means the course example no longer presents a failing translation setup and the updated instructions are clear.
