Add .NET 9 to CI

Test the in-development .NET 9 RPM as a way to find out how well
dotnet-regular-tests are working against .NET 9.

Also update templates-test to support a new set of templates that
require an existing project before `dotnet new $template` will work.
This includes a template new to .NET 9 (mstest-class) but also a
template that didn't behave this way in .NET 8 (nunit-test).
