Subject: [PATCH] Fix Docker build context for base image in GitHub workflow

The base image was built locally but not accessible to subsequent build steps.
Added build-contexts to pass the locally-loaded base image to both autoindex
and scip-ruby image builds, resolving the 'pull access denied' error.
