docs: Convert sequence types to bundles
  
      This converter automatically constructs a :py:class:`~.Bundle`
      from any :py:class:`tuple`, :py:class:`list` or :py:class:`set`
      encountered during linking.
      The following two lines produce the same chain:
  
      .. code:: python
  
          a >> [b, c, d] >> e
          a >> Bundle((b, c, d)) >> e
