Frugal score deprecations
Hi @Ierezell, thanks for reporting.

I'm making a PR to suppress those logs from the terminal. 
## Describe the bug
The frugal score returns a really verbose output with warnings that can be easily changed. 

## Steps to reproduce the bug
```python
# Sample code to reproduce the bug
from datasets.load import load_metric

frugal = load_metric("frugalscore")
frugal.compute(predictions=["Do you like spinachis"], references=["Do you like spinach"])
```

## Expected results
A clear and concise description of the expected results.
```
{'scores': [0.9946]}
```

## Actual results
Specify the actual results or traceback.
```
PyTorch: setting up devices
The default value for the training argument `--report_to` will change in v5 (from all installed integrations to none). In v5, you will need to use `--report_to all` to get the same behavior as now. You should start updating your code and make this info disappear :-).

The following columns in the test set  don't have a corresponding argument in `BertForSequenceClassification.forward` and have been ignored: sentence2, sentence1. If sentence2, sentence1 are not expected by `BertForSequenceClassification.forward`,  you can safely ignore this message.
