[docker] allow docker container builds to pass when security advistory (#6662)

Right now, we test the container at the end of the build rather than
before publishing so while we decouple that work, we should not fail
the build step if a security advisory was found - it's too late, the
containers are released so we should instead catch the advisory and
that will allow our release pipeline to continue
