update `use_auth_token` -> `token`
# What does this PR do?

Fix #25008

@sgugger This should be ready for a review. There are still a few places that use `use_auth_token`, but only during the calls to relevant methods.

I will change those calls to use `token` before merge.
_The documentation is not available anymore as the PR was closed or merged._<|||||>In some training example script, (for example, `examples/tensorflow/contrastive-image-text/run_clip.py`) there are 

```python
    use_auth_token: bool = field(
        default=False,
        metadata={
            "help": (
                "Will use the token generated when running `huggingface-cli login` (necessary to use this script "
                "with private models)."
            )
        },
    )
```
Do you have any comment on how we should do with them?

Change everything to use `token` but still need to accept `use_auth_token`?
