tdf#143028 DOCX export: fix RangeY regression of preset shapes

Use property name "RangeYMaximum" instead of "RangeXMaximum"
in GetAdjustmentPointYValue().

Regression from commit 99a459dfdfd9f82ed3506708e131dd52a1a62384
(tdf#143028 DOCX: fix corrupt export of shape "bracePair" etc.)

Thanks to Regina Henschel for reporting the problem.
