Make it possible to publish --self-contained MicroBenchmarks.csproj

[adamsitnik]

As of today, it's impossible to publish a self-contained version of MicroBenchmarks.csproj due to a package downgrade issue.

The source of issues are the 3rd party JSON serializer benchmarks that use Jil, which uses Sigil which uses a very old version of NETStandard.Library 1.5.0-rc2-24027 which references Microsoft.Win32.Primitives 4.0.1-rc2-24027.

We can't update Jil because we already use the latest version. I think that we should rather not remove it because it's one of the fastest JSON serializers and it's good to have it for competitive comparison with System.Text.Json.

So my proposal is just to listen to the compiler and add both references in explicit way.

@billwert this is going to help me with making it possible to run the performance repo microbenchmarks with @sebastienros infrastructure and in the future might become usefull if we decide to separate benchmarks build and run into two separate steps (we are going to need a publish, self-contained project then)

I imagine this has no impact on any measurements, so it seems fine.
