Fix Tests before 24.2 Release

[LucaCinquini]

Purpose

• This PR fixes the integration and smoke tests for the "unity-sps" repository before issuing release 24.2

Proposed Changes

• [CHANGE] The integration test now uses the SBG Preprocess workflow, instead of testing the SBG end-to-end step-by-step workflow. The latter often crashes because of running out of ephemeral space, and will have to be debugged and fixed separately
• [CHANGE] Commenting out the smoke tests for the unity-venue-test until we can again deploy SPS there

Issues

• No issues, just fixing the tests

Testing

• Integration and smoke tests work on this branch
