Update GitHub Actions release workflows to use the SNOWLUMA_TOKEN secret instead of DOCKER_RELEASE_TOKEN. Changed the github-token input in .github/workflows/release.yml and .github/workflows/dispatch-docker-release.yml for the docker release steps.
Introduce a manual re-dispatch workflow and wire automatic dispatch from releases to the Docker workflow. dispatch-docker-release.yml was converted to a workflow_dispatch-based "Re-dispatch Docker Release" that accepts snowluma_tag, docker_image_override and platforms_override inputs and forwards them (plus source repository) to the downstream docker-image.yml in the Docker release repo. release.yml gains a dispatch-docker job that runs after the release job and uses a PAT to invoke the same downstream workflow for newly published tags. These changes let maintainers rebuild Docker images for existing tags (e.g. to fix Dockerfile issues or rotate credentials) without re-tagging, and ensure the downstream dispatch runs under the configured token.
Switch the release dispatch to call actions.createWorkflowDispatch instead of repos.createDispatchEvent because the target repo only listens for workflow_dispatch on its docker workflow. Add env vars DOCKER_PLATFORMS, DOCKER_WORKFLOW and DOCKER_REF (with sensible defaults) and pass image, tag, push and platforms as inputs. Update log output to include workflow, ref, image, tag and platforms.
Trigger the external Docker release pipeline when a SnowLuma version tag is pushed.
Keep Docker image and release target configuration in the SnowLuma environment.
