What needs to happen?

Since https://lists.apache.org/thread/j2njqyb68zlq7fb59zzkdtv86dnk1j5w , Spark runner now supports Java 11, however, Samza runner still remained on Samza 1.6.0

As part of #31678, Current Samza runner will stop working after Beam removing Java 8 support, see #32208 for context. Even before that, Samza Xlang runner tests will stop working once we upgrade Gradle plugin versions that need Java11+

As a result, Samza runner is going to be removed prior to Beam 3 release unless it is upgraded to Samza 1.8.0+
