Setting completionPortThreads with runtimeconfig.json

### Type of issue

### Description

**Issue description**

Hello,
The documentation for setting the ThreadPool MinThreads (https://learn.microsoft.com/en-us/dotnet/core/runtime-config/threading) mentions it's equivalent to ThreadPool.SetMinThreads method https://learn.microsoft.com/en-us/dotnet/api/system.threading.threadpool.setminthreads?view=net-7.0

This method has two parameters - int workerThreads, int completionPortThreads.

Is it possible to set the completionPortThreads with the runtime config? If so, how?

Alternatively, if the completionPortThreads setting does not matter in the new implementations of .NET, could the documents be updated with a remark about this parameter?

**Target framework**

- [x] .NET Core
- [ ] .NET Framework
- [ ] .NET Standard
