Started backport to release/9.0.1xx as that PR is higher priority and will likely need different changes, or no additional changes at all.

Package versioning for runtime packages is older than what was used in RC1 build we are using for bootstrap.

The build fails in roslyn-analyzers repo. This repo is built before roslyn, so it resolves MicrosoftCodeAnalysis from PSB. This package has a dependency on System.Composition with RC1 version 9.0.0-rc.1.24431.7. The project has a direct dependency on this package so it picks the live-built one, even though it is older than the version in PSB. Builds in main produce this and other runtime packages with version 9.0.0-rc.1.24414.5, as runtime has not flowed to main in a while.

/src/git/dotnet/src/roslyn-analyzers/src/Tools/GenerateDocumentationAndConfigFilesForBrokenRuntime/GenerateDocumentationAndConfigFilesForBrokenRuntime.csproj error NU1605: Warning As Error: Detected package downgrade: System.Composition from 9.0.0-rc.1.24431.7 to 9.0.0-rc.1.24414.5. Reference the package directly from the project to select a different version. 
 GenerateDocumentationAndConfigFilesForBrokenRuntime -> Microsoft.CodeAnalysis 4.12.0-2.24422.8 -> System.Composition (>= 9.0.0-rc.1.24431.7)

This is obsolete. Main will need to be rebootstrapped with a net 10.0 SDK.
