Don't wait for workflows to publish Docker image

It keeps the wait step on PRs, but not on tag pushes or manual workflow
dispatches. This prevents CI failures on master from blocking our
ability to publish a docker image, as was the case with coveralls.io
errors the last few days due to circumstances out of our control.
