CI: Some tags still triggering CE jobs starting in Phase 5 of CNG
Summary
Recent improvements to the CI for the CNG have reduced the number of unwarranted pipelines on .com vs dev, however we're still seeing a few instances of CNG pipelines being triggered partially on .com.
By partially, I mean they are running only stages from phase-five
onward, which will always fail because they depend on images before them. We should prevent all jobs from triggering in these cases, not simply 'most'.
