Add server message to HTTPError (if any)

[Wauplin]

Related to #1012 and https://github.com/huggingface/moon-landing/issues/3703.

Now the error message returned by the server is added to the HTTPError. Example for a gated dataset:

from huggingface_hub import snapshot_download

snapshot_download(
    "sbrandeis/gated-fields",
    repo_type="dataset",
    use_auth_token="xxx",
)

Traceback (most recent call last):

Access to dataset sbrandeis/gated-fields is restricted and you are not in the authorized list. Visit https://huggingface.co/datasets/sbrandeis/gated-fields to ask for access.

@SBrandeis @Pierrci how would you test that ? I wanted to create a gated repo on the staging platform but since it would be created by the user itself, the gate is automatically open. And as far as I understand, when we use the production server in the CI it's only for public and open repositories (no token).
