[Wav2Vec2] Fix `None` loss in docstring for Wav2Vec2ForPreTraining
# What does this PR do?

- [ ] It fixes the Nan value returned in the contrastive loss of [Wav2Vec2ForPreTraining](https://huggingface.co/docs/transformers/v4.21.3/en/model_doc/wav2vec2#transformers.Wav2Vec2ForPreTraining)  .
- [ ] Adding sampled_negative_indices as a target allows Wav2Vec2ForPreTraining to calculate the loss. 

_The documentation is not available anymore as the PR was closed or merged._<|||||>Great! Now that we've established the problem:

> loss is `None` as `sampled_negative_indices` is omitted from the args of the model

and verified the fix:

> forward `sampled_negative_indices` to the model

we can touch-up this PR and get it merged!

We'll need to do two things:
1. Remove the erroneous file [src/transformers/models/test.py](https://github.com/huggingface/transformers/pull/18960/files/e94a4d4e7bb108aeba8daafc3de7b58fc5048838#diff-dc9af87a30bbbc682dfaf00796e992367511d96095a2f0a46a8da06a948a7050)
2. Code quality: you can do this simply by running `make style` from the root of the Transformers repo 🤗

Let me know if you have any questions! Cheers!<|||||>Hello @sanchit-gandhi  Thanks for the help , I am still having some issue even when I make sure that I had installed all the necessary packages I am still having this error . 
Even `pip install black[jupyter]` is installed and when I run `make style`i have the same error here : 
```py

Skipping .ipynb files as Jupyter dependencies are not installed.
You can fix this by running ``pip install black[jupyter]``
would reformat examples/research_projects/lxmert/modeling_frcnn.p
...
```<|||||>Hey @abdouaziz. Thanks for removing the erroneous file :) Don't worry about the `.ipynb` warning as we've not changed any Python notebooks! Looks like something else is up with `make style` though - we have 567 files changed in this PR! There should only be 2 files changed (wav2vec2 and wav2vec2-conformer).

Could you try the following in turn and check whether the number of files changed drops back down to 2 after each step:
1. Rebasing onto main:
```
git fetch upstream
git rebase upstream/main
```
And then running `make style`.
2. Updating HF doc builder https://pypi.org/project/hf-doc-builder/
```
pip install --upgrade hf-doc-builder
```
And then running `make style`.

If that doesn't fix it we can try some other hacks!

<|||||>Hey @abdouaziz - sorry this has been so arduous! Are you still interested in completing this PR? Feel free to open a new one if you wish and we can go from there!<|||||>>
