chore(ci): concurrency group for integration test (#93)

Add a concurrency group for integration test workflow. Integration
tests are flaky otherwise. Workflow is now triggered automatically
without approval, but will queue up if there's other runs active
at the time.

Integration tests depend on the test workflow to pass.
