Invetigate intermittent integration test failure after lotus API does not start

[masih]

Sometimes lotus node API does not start after 10 minutes. It should usually start within 5 minutes.

Example:

• https://github.com/filecoin-project/motion/actions/runs/6154722034/job/16700515092

Seems like this error occurs when proof parameter download takes longer than expected. Quick fix would be to increase timeouts, and ideally we should separate validation steps in build to clearly communicate the failure cause
