Akka.TestKit.Xunit Xunit3 support #7603
Description
Is your feature request related to a problem? Please describe.
Xunit3 is out - we should probably add support for it.
Describe the solution you'd like
IMHO - bump the Akka.TestKit.Xunit package to support it and leave the Xunit2 package as-is.
Describe alternatives you've considered
We could ship a new Xunit3 package instead - that leaves the issue of what do about the old Xunit package though.
