[WIP] Fix failing GitHub Actions workflow for integration (#15731)

* Initial plan

* Fix Docker daemon check in integration tests

- Update TestValidateContainerImages to check Docker daemon status
- Update TestValidateDockerImage to check Docker daemon status
- Use isDockerDaemonRunning() function to match validation code behavior
- Tests now properly skip when Docker daemon is not running (not just when binary is missing)
