Fix tests broken by timing change

[paulyuk]

Description

Tests now fail in state management CI/CD because of the final dapr stop on the single service. in 1.12.0 the service was still available to stop by the time this step ran. Now, the service is already gone, so stop fails. The fix is to keep the stop in the readme, but remove it from the test workflow which will run it in CI.
