sdk publishing is broken

[ViktorHofer]

.sha512 files have the wrong filename (they are named the same as the original files) and are placed in the wrong folder.

I think that's the reason for the broken official builds: https://dnceng.visualstudio.com/internal/_build?definitionId=140

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

The fix in arcade was merged. Let me know if this should stay open for some reason (like tracking flow of the fix).
