Workflow fixes and changes (#105)

- The rolling build is detecting that there is a newer base image
available, but it's not properly triggering the build and publish step.
This change attempts to fix that issue by simplifying the workflow and
properly propagating and checking the output value.
- Updated build job names.
- Added the ability to skip the CI build by specifying "ci skip" in the
commit message.
