[pom] Override parent until 49 with enforcer / impsort adjustments and remove changing to java 16 with java 16+

Only tests needed the higher value, remove that as unnecessary.  Tests remain compliant with java 17+ at this point.  This further fixes the resulting binary so it doesn't matter what jvm we use to release with and no extra overrides are necessary
