feat: update cimg-orb with testing namespace workflow (#308)

with this change, the orb now implements additional steps to ensure
there are no false positives in terms of building images.
 
1) checks to see if the image was actually built, based off what should
be built
2) pushes to our testing namespace to make sure it actually is/can be
pushed to dockerhub
