SDK 8.0.304 references unpublished version of .NET 6

[caaavik-msft]

Describe the bug

When using the .NET 8.0.304 SDK, and then attempting to build a project that targets net6.0, the build fails because it tries to use version 6.0.33 which is not on any nuget feeds yet (nuget.org or dotnet-public).

This is causing the dotnet-performance test runs against .NET 8 scenarios to fail currently (link to example failure). The issue does not reproduce when installing the latest daily .NET 9 SDK which uses 6.0.32.

I don't know enough about the .NET release process to know if the bug here is with the SDK referencing a version that shouldn't be referenced, or that 6.0.33 should be published to nuget.org but isn't.

To Reproduce

1. Install latest daily version of .NET 8 (which at the time of this issue is installing 8.0.304):

.\dotnet-install.ps1 -InstallDir .\dotnet -Architecture x64 -Channel 8.0 -Quality daily

2. Update your path to use the downloaded SDK
3. Create a console app:

dotnet new console -o MyApp

4. Edit MyApp.csproj to use net6.0 as the target framework
5. Run dotnet build

8.0.304 is not a stable release yet (you're explicitly using -Quality daily in the install script) so this is kind of expected, you'd need additional feeds to get the not-yet-published version of the packages.

[caaavik-msft]

Thanks for the response, we will try get the additional feeds set up then for our pipelines.
