openpyxl.chart.Series is missing from the stub #16209

In openpyxl's chart/__init__.py, Series is exported as:

from .series_factory import SeriesFactory as Series

However, the corresponding export is missing from typeshed's openpyxl/chart/__init__.pyi.
As a result, type checkers report an error for valid code such as:

from openpyxl.chart import Series

This import is also used in the official openpyxl documentation.
I think the stub should include:

from .series_factory import SeriesFactory as Series
