message: ci: publish canary builder with proper tag
  Previously, the builder would not be published with
  a tag, meaning that any time that the canary build
  was triggered, it would publish `ethereumoptimism/builder:latest`.
  This clobbers the release from `master` which may have downstream
  effects.
