class_docstr: A stateless singleton that proxies ``st.query_params`` interactions
  to the current script thread's QueryParams instance.

docstr: Get a list of all query parameter values associated to a given key.
  
  When a key is repeated as a query parameter within the URL, this method
  allows all values to be obtained. In contrast, dict-like methods only
  retrieve the last value when a key is repeated in the URL.
  
  Parameters
  ----------
  key: str
      The label of the query parameter in the URL.
  
  Returns
  -------
  List[str]
      A list of values associated to the given key. May return zero, one,
      or multiple values.
