[CTM-449] Update workbench libs for swagger-ui

[calypsomatic]

Jira ticket: https://broadworkbench.atlassian.net/browse/CTM-449

Summary of changes

What

• Update workbench-oauth2 to 0.9-be59bd7 to pick up a swagger-ui security fix (5.26.2 → 5.32.1). The new workbench-libs commit is on the develop branch which had already bumped http4s from 0.23.33 to 1.0.0-M38, so we needed to upgrade Leonardo's own http4s dependencies to match. http4s-prometheus-metrics was bumped to its corresponding 1.0.0-M38 release, and http4s-ember-client was added as an explicit dependency since it's no longer pulled in transitively by workbench-libs at this version.
