Add a core test logger to help capture the MSSQL container output (#28472)

* Add a core test logger to help capture the MSSQL container output

 - I believe the if t.Failed prevents the logging of the container
   logging as when executed the test isn't considered failed yet.
 - Use a test core logger so that we can capture the container output
   all the time and get it from the captured log files when the test
   fails

* bump image tag to 2022-latest
