Minor fixes to new CI workflow. (#59697)

Dest S3 & Dest S3-data-lake were missing a poe file.
Set the test workflow to match the current GHA instance type. Otherwise we aren't able to parallelise effectively, and tests take too long to run. See here for current settings. Instead of 5 hours, I'm using 1 hour to start.
