[i18n-ar] Translated file : docs/source/ar/tasks/token_classification.md into Arabic
Author: AhmedAlmaghz
Pull request: yes

## What does this PR do?
Translated the `docs/source/ar/tasks/token_classification.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.
