Changes proposed in this PR:
In `actions-docker-build` we [pass](05c370a26e/scripts/docker_build (L49)) `PRODUCT_VERSION` to the docker build command. Since this was not set, the label did not populate properly which is used in a comparison to determine the `minor-latest` and `latest` docker image tags.
How I've tested this PR:
- build the image up to the point of label creation and pass in `--build-arg PRODUCT_VERSION=1.2.3`
- inspect the image for the label with the above command
How I expect reviewers to test this PR:
- same as above
