Ratchet up to newer baseline

[colindean]

Target's internal baseline is rebasing onto these facts:

• Ubuntu
• JDK 17
• Scala 2.13 (or 2.12)
• Spark 3.5.1

#166 will handle Spark 3.5.1 and sets the stage for JDK 17. It enables Scala 2.12, too, but keeps Scala 2.11. We'll want to roll off Scala 2.11 and onboard 2.13.

I don't think we've got anything that cares about the underlying distro.

After #166 is merged, we'll need to do some testing and work to ensure operability on JDK 17, including bumping CI workflows.
