Skipped test - test-data-combined

# `loadDataSetsFromExcel()` does not work for non-Windows platforms
skip_on_os("linux")
skip_on_ci()

With .NET8, do we expect these tests to work? @Yuri05 @rwmcintosh @benjaperez1983

skip_on_ci() can be removed in general, or are they also critical for GHA? @Felixmil

I think we'll need to review them one by one. I suggest that we first get no failure with current active test then proceed.

Not skipped any more - all passing.
