Package and Target Framework Updates (#24)

 - Update test and benchmarks projects to `net6.0`
 - Update NerdBank and SourceLink packages (NerdBank currently explodes on latest macOS)
 - Update `Microsoft.Extensions.Configuration` in the configuration project
 - Use `FrameworkReference` in unit test project (rather than referencing Kestrel package directly)
 - Fix `Http2Tests` to work reliably on macOS
