📝 Walkthrough

Walkthrough

The docker-release.yml workflow file was updated to use version 7 of the docker/build-push-action GitHub Actions step, replacing the previous version 6. The step configuration, including its identifier and all input parameters (context, platforms, push, sbom, provenance, labels, and tags), remains unchanged. This is a single-line modification that updates only the action reference commit hash.
