Enable tests on netcoreapp3.1 (#520)

* AssemblyVersionInfo task: Log error when targetting an unsupported language.

* Skip SevenZipNet dependency on .NET Core

* Enable tests on netcoreapp3.1

RuntimePath is ./runtimes instead of ../runtimes

* Skip NativeVersionInfo_CreateNativeResourceDll on .NET Core

* Update src/NerdBank.GitVersioning.Tests/BuildIntegrationTests.cs
