docs: Returns an amended copy of the proxies dictionary - used by `requests`,
      it will disable the proxy if the uri provided is to be reached directly.
      :param proxies A dict with existing proxies: `https`, `http`, and `no` are potential keys.
      :param uri URI to determine if a proxy is necessary or not.
      :param skip_proxy If `True`, the returned proxy dictionary will disable all proxies.
