Fixes #127687
Servicing branches do not create optimization data packages. There were no optimization builds until february and we didn't notice the channel assignment in the optimization repo was wrong, so bits were flowing to places where changes weren't expected. Roll back to the LKG that is trained against .NET 10. Risk is low - this is the data used for 10.0.0.
