fix: pass Docker tag variables as env vars instead of build args

RELEASE_VERSION, DOCKERHUB_REPO, and DOCKERHUB_IMG are HCL variables
used in docker-bake.hcl tag templates. Passing them via *.args.* only
sets Docker build args, not HCL variables, so the tags defaulted to
"latest" instead of the actual version.
