UIA: actually use ExcelTable NVDAObject for Excel tables. Accidentally left out of pr #14165 (#14223)
Summary of the issue:
PR #14165 was to make it so that when moving outside of a table in Excel, NVDA would announce exiting the table.
However, part of the code was accidentally left out of the pr, namely the code to choose the ExcelTable class for Excel table elements.
Description of user facing changes
NVDA will now really report exiting tables in Microsoft Excel.
Description of development approach
UIA NVDAObject's findOverlayClasses includes the ExcelTable NVDAObject class for Excel tables.
Testing strategy:
Performed steps for pr #14165.
