Check if target workflow is enabled before triggering front sync (#81432)

Now, if the workflow is disabled, the sync trigger is skipped with clear
logging. The on-call person should be aware that the workflow is
disabled and can manually rerun the sync once the workflow is
re-enabled.
I tested this by commenting out the tests and just running the check if
workflow is enabled step and it worked:
