.NET 9 SDK seems mandatory to build the application because of dependancy : Microsoft.CodeAnalysis.CSharp.BannedApiAnalyzers.dll

[juliengalego]

Describe the bug
When I build my .NET Core 8 Application on Azure Devops, it crashes because it needs .NET 9 SDK

"An instance of analyzer Microsoft.CodeAnalysis.CSharp.BannedApiAnalyzers.CSharpRestrictedInternalsVisibleToAnalyzer cannot be created from /home/vsts/.nuget/packages/microsoft.codeanalysis.bannedapianalyzers/4.14.0/analyzers/dotnet/cs/Microsoft.CodeAnalysis.CSharp.BannedApiAnalyzers.dll : Could not load file or assembly 'System.Collections.Immutable, Version=9.0.0.0"

To Reproduce

• task: DotNetCoreCLI@2
  displayName: 'Publish Web'
  inputs:
  command: publish
  projects: $(project-api-csproj)
  arguments: '--configuration $(BuildConfiguration) --output $(build.artifactstagingdirectory) /p:BranchName=$(Build.SourceBranchName) '
  zipAfterPublish: True
  verbosityRestore: Detailed
  verbosityPack: Detailed

Expected behavior
If a strong dependance to .NET 9 is expected, it should be visible. We also need to know what version is compatible to .NET 8

Environment (please complete the following information):

Additional context
Add any other context about the problem here.

Versions 1.1.13 and below should be compatible with .NET SDK 8.

Note that you can use .NET SDK 9 to build .NET 8 application. SDK and TFM can be different.
