CI: add Windows Integration Tests for .NET (#1704)

* CI: add Windows Integration Tests for .NET

see https://github.com/sshnet/SSH.NET/pull/1702#issuecomment-3342506642

* fix podman setup with Windows and .NET

* debug

* x

* x

* x

* revert

* Run Windows .NET tests in separate job

so they run in parallel and we avoid the Common_CreateMoreChannelsThanMaxSessions test failure.

* fix coverlet artifacts

* fix missing PermitTTY in RemoteSshdConfig Reset

this fixes a test failure in Common_CreateMoreChannelsThanMaxSessions
when running the tests multiple times against the same SSH server
instance.

see https://github.com/sshnet/SSH.NET/pull/1704#issuecomment-3343210311

* speed up Windows tests

turns out this is caused by DNS resolution taking about
2 seconds on every new connection...

* add windows integration tests to Publish needs:
