[`training`] Pass `steps`/`epoch`/`output_path` to Evaluator during training

[tomaarsen]

Resolves #3062

Hello!

Pull Request overview

• Pass steps/epoch/output_path to Evaluator during training
  • Both for the deprecated model.fit() and the SentenceTransformerTrainer
• Fix EmbeddingSimilarityEvaluator and NanoBEIREvaluator who failed when writing to disk

Details

The model.fit nor SentenceTransformerTrainer passed all available parameters down to the evaluator(s). In particular, the output_path wasn't sent, which meant that no csv files could be written for the evaluators. Beyond that, 2 evaluators failed when writing to disk. Some better tests for the evaluators would be appreciated, as this could've been caught.

Gladly! You can use this already with:

pip install git+https://github.com/UKPLab/sentence-transformers.git

And otherwise this will be included in the next release.
