As noted in:

• Setup Java does not ensure that sbt is installed on Ubuntu 24 setup-java#712

sbt is no longer included in the latest macOS / ubuntu runners which means the workflow as is will not work.

It should either be removed or fixed.

in actions/setup-java#712 (comment), @eed3si9n suggested https://github.com/sbt/setup-sbt, that seems like a reasonable fix.
