Properly install ruamel-yaml for windows CI
@lhoestq I would say this does not "properly" install `ruamel-yaml`, but the contrary, you overwrite the previous version without desinstalling it first.

According to `pip` docs:
>  This can break your system if the existing package is of a different version or was installed with a different package manager!

Note that our case fulfills both conditions:
- the installing version (`0.17.16`) is different from the existing one (`0.15.87`)
- you are installing using `pip` (`setuptools`), whereas the exisitng version was installed using `distutils`

That is why I did not fix the issue this way, made a hotfix pinning `huggingface_hub` (#3025), while looking for a permanent solution for the issue. Yea I did this because we need the latest version of `huggingface_hub` for #2986 and because I didn't want to ssh to the windows worker x)
Maybe it can be fixed by installing it with conda - let me try Oh yea it may not work since it was first installed with distutils
