🐛 Bugfix: Rename eval_strategy → evaluation_strategy in TrainingArguments

This PR corrects an API mismatch in the TrainingArguments dataclass where the constructor expected eval_strategy, but Trainer, config files, and CLI use evaluation_strategy.

✅ Changes

• Renames the field eval_strategy → evaluation_strategy
• Updates all internal logic and references
• Corrects docstrings and argument descriptions
• Validated via inspect.signature(TrainingArguments.__init__)
• Tested with full reinstallation and cache invalidation

🧪 Reproduction (Before Fix)

TrainingArguments(evaluation_strategy="epoch")
# ❌ TypeError: got an unexpected keyword argument 'evaluation_strategy'

Thanks for the PR, and sorry it didn't make it in! This branch is based on v4, and v5 is very different, so rather than rebasing we'd love to invite you to open a new PR against main using our latest tools and good practices:

• Transformers tenets
• mlinter and the modeling rules it enforces (make typing)
• Modular transformers
• Contributing guide

Closing this one in the meantime, thanks again!
