Validate that script test can detect pod failures

Bug

Description

1. Validate that script test can detect external secret operator pod failures. Recent renovate MR updated the CRDs for ESO to v1 from v1beta. This caused the external secrets operator pod to crashloop in the upgrade job. A failed test would have caught this in CI but the test passed.

Failed package pipeline here Package pipeline line indicating successful test after crashlooping pod -> https://repo1.dso.mil/big-bang/product/packages/external-secrets/-/jobs/44947133#L2187

2. Troubleshoot Big Bang umbrella repo pipelines to figure out why the script test is not running. Here's a BB MR pipeline job where tests are not running for ESO https://repo1.dso.mil/big-bang/bigbang/-/jobs/45070754#L6880
