[Core] remove resume_download from Hub related stuff

[sayakpaul]

What does this PR do?

To not have to incur:

huggingface_hub/file_download.py:1132: FutureWarning: `resume_download` is deprecated and will be removed in version 1.0.0. Downloads always resume when possible. If you want to force a new download, use `force_download=True`.

[HuggingFaceDocBuilderDev]

The docs for this PR live here. All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.

Thanks for taking care of removing those @sayakpaul. I'm linking #7843 and #8267 which are related PRs (the ones that should have already removed the deprecation warnings). Removing resume_download altogether is even better since it'll also us to remove it from huggingface_hub in the future.

Last thing: do you want to remove resume_download mention from docstrings as well? We have this message for now but if we remove them already, then let's remove the docs as well?

[sayakpaul]

@Wauplin removed from docstrings as well.
