Setting the version in nox to just '3.10' appears to allow 3.10.0b2 to run for me

github CI appears to require full beta version number which is incompatably with how nox wants the version passed in.
Changed CI to run test targets without specifying version and relying on nox to auto-skip unsupported versions
Added Python 3.10 to azure pipelines.
