### Description
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. A change merged in today (https://github.com/hashicorp/actions-docker-build/pull/25) checks for this value being set in the docker build action, and errors out if it does not exist. This will unfortunately cause build failures in this repo on merges to `main`.
