    HTTPError to inherit from for any custom HTTP Error raised in HF Hub.

    Any HTTPError is converted at least into a `HfHubHTTPError`. If some information is
    sent back by the server, it will be added to the error message.

    Added details:
    - Request id from "X-Request-Id" header if exists. If not, fallback to "X-Amzn-Trace-Id" header if exists.
    - Server error message from the header "X-Error-Message".
    - Server error message if we can found one in the response body.

    Example:
    ```py
        import httpx
        from huggingface_hub.utils import get_session, hf_raise_for_status, HfHubHTTPError

        response = get_session().post(...)
