[release/9.0.1xx-preview6] [dotnet] Fix workload reference to .NET 8 …

…packages. (#20795)

The stable .NET 8 workload we're releasing is calling its Sdk pack
'Microsoft.iOS.Sdk.net8'. This means the pack has to be named the same
across
everything we're releasing, so special-case the Sdk pack in preview 6 to
use
the same Sdk pack name.
