use read-only Mapping for values dictionary type
Improved typing for the mapping passed to :meth:`.UpdateBase.values` to be
more open-ended about collection type, by indicating read-only ``Mapping``
instead of writeable ``Dict``, the latter of which would error out under
typing tools on too limited of a key type.
Fixes: #9376
Change-Id: Ib7fdbba05ca7e1082409e1b5616e6a010262f032
