 - druid: Add `37.0.0` ([#1535]).
 - hbase: Add `2.6.6` ([#1547]).

-- spark: Bake the OpenLineage Spark listener (`1.51.0`) into the Spark images under the dedicated directory `/stackable/spark/openlineage/` (off the `extra-jars` classpath), enabling the OpenLineage MVP in the operator. The Scala 2.13 build (`openlineage-spark_2.13`) is used for the `4.1.x` images and the Scala 2.12 build (`openlineage-spark_2.12`) for the `3.5.x` images ([#XXXX]).
