Sample code for Nexus Standalone

* Sample code for Workflow Streams

* Use SDK 1.37.0-SNAPSHOT from the Central snapshots repository

SDK main now publishes 1.37.0-SNAPSHOT, and snapshots moved from
oss.sonatype.org to central.sonatype.com when OSSRH was decommissioned.

* Add non-blocking listener scenario to Workflow Streams sample

Scenario 2 subscribes with a WorkflowStreamListener instead of iterating:
two order workflows are consumed concurrently on one shared executor
thread, with CompletionStage-based backpressure and done futures instead
of a parked thread per subscription. Later scenarios renumbered, and the
stale SDK snapshot note updated for the Central snapshots repository.

* Use released SDK 1.37.0 instead of snapshot

The temporal-workflowstreams module is now in the tagged 1.37.0 release
on Maven Central, so drop the -SNAPSHOT pin and the snapshots repository.
