DotMake.CommandLine v1.8.4

• Updated to latest daily build 2.0.0-beta4.24126.1 of System.CommandLine.

• Fixed compiler error related to CliServiceProviderExtensions and CliServiceCollectionExtensions when project is referenced
  by another project. Class conflict errors occur due to same namespace in different assemblies.

  This can't be fixed via PrivateAssets in PackageReference because although default value is "contentfiles;analyzers;build",
  source generator still flows to the parent project via ProjectReference and PrivateAssets="all" prevents flow of
  source generator but it also prevents flow of "compile" so it becomes useless.

  First attempt to fix (in v1.8.3), was making CliServiceProviderExtensions and CliServiceCollectionExtensions
  classes internal but the problem resurfaces if user adds InternalsVisibleTo attribute in child project.

  So we finally solve this problem, by detecting if current compilation is a parent project in the solution,
  if so we do not inject feature extensions as they already come transitively from the child project.
  This way we can also keep CliServiceProviderExtensions and CliServiceCollectionExtensions classes public.
