XMLUnit.NET 2.11.0 released

Back when I releasedXMLUnit.NET 2.10.0 I claimed the NUnit 3.x constraints would nowsupport NUnit 4.x as well. Unfortunately I never really tested this and it turns out to be wrong. NUnit 4.x is a major release and it has broken backwards compatibility (it is a major version, after all) in a way that doesn't seem to allow using the same constraint implementation for 3.x and 4.x.

XMLUnit 2.11.0 adds a new XMLUnit.NUnit4.Constraints package with constraints for NUnit 4.x. This package requires at least .NET 6 or .NET Framework 4.6.2 - the minimum frameworks supported by NUnit 4.x.
