tools-in-path should use framework version, not sdk version. (#333)

Since the latest release of dotnet 8, 8.0.101, tools-in-path has been failing
as even though there is a version of dotnet-ef for 8.0.1, it expects the dotnet framework installed to also be 8.0.1,
whereas the framework used in dotnet 8.0.1 is still 8.0.0 which causes a compatibility error and a test failure.
Instead of installing the version of dotnet-ef that matches the installed sdk version,
the test should download the version of dotnet-ef that matches the installed framework.
