Subject: [PATCH 2/3] GitHub: split git tag and image tag

This commit allows us to have different values for the git tag that is
checked out (RELEASE_VERSION) and the image tag that we push
(IMAGE_TAG).

Subject: [PATCH 3/3] GitHub: add nightly schedule to Docker CD workflow

Added a daily schedule to the Docker workflow to automate builds and
pushes of the `daily-testing` image. This change introduces a new cron
job that runs every day at midnight (UTC) and triggers the workflow.
