[i18n-ar] Translated file: docs/source/ar/tasks/multiple_choice.md into Arabic

[AhmedAlmaghz]

What does this PR do?

Translated the docs/source/ar/tasks/multiple_choice.md file of the documentation to Arabic العربية. I use transformers for my side-project and wanted to contribute. As a beginner, this seemed appropriate.

Some questions:

• I can't access the pr documentation endpoint for Arabic العربية. Is there a missing step?
• I left all the other files alone after copying the English docs. Is this acceptable for future updates or should I add contents to the _toctree.yml only when translation is complete? Should I delete all other files for a cleaner review?
• In Arabic, people use both Transformer and المحولات to describe the model. However, as this is more of a product of HuggingFace I opted not to translate it. May you please let me know which you would prefer?

Thank you in advance for your review.
