Bug: The workflow triggers on the main branch but checks for master in its conditional logic, which will prevent Docker images from being published on push.
_{Severity: HIGH}

Suggested Fix

Align the branch names. Either change the trigger branches in the on: block from main to master, or change the conditional checks from refs/heads/master to refs/heads/main to match the trigger.

Potential issue: The workflow is configured to trigger on pushes to the `main` branch.
However, the conditional logic for setting the environment and publishing the image
checks if the branch is `refs/heads/master`. Because of this mismatch, when code is
pushed to `main`, the `publish_image` input will evaluate to `false` and the environment
will be set to read-only (`gcp-artifacts-ro`). As a result, Docker images will be built
but will silently fail to publish to the artifact registry.
