Can you install `ruff==0.1.5` and run `make style` & `make fix-copies` as well?

Result of `make fix-copies` has inconsistencies, so I still have to check the `fix-copies` code.

@ArthurZucker @fxmarty Just added sdpa to all of these models that use ViT as base. 
All tests passed except for one
```
FAILED tests/models/videomae/test_modeling_videomae.py::VideoMAEModelTest::test_eager_matches_sdpa_inference_1_bfloat16 - RuntimeError: "mse_cpu" not implemented for 'BFloat16'
```

Can you also rebase on main to make sure CI is full green! 

Is there any update on this PR ? I d be happy to help with the remaining tasks (rebase + running the tests) if needs be :) 

Hi @hyenal, as this PR hasn't had any activity for over a month, feel free to open another PR with these changes and ping us for review when ready!

Thanks a lot for the reply, I d like to give the author a chance to reply to my message before submitting a new PR (even adding me as a contributor to the repo would work @lyaronskaya ).
Otherwise I will submit the PR by the end of the week :) 

Hi @hyenal! I’m little busy, and you can take it over. I appreciate your help
