name: Docker image

# Builds the multi-arch ghcr.io/kucherenko/jscpd image from the release
# binaries (see the root Dockerfile) and pushes it with provenance, SBOM and a
# GitHub build attestation.
#
# Releases created with GITHUB_TOKEN do not trigger `release` events, so the
# release workflow calls this one (workflow_call). The `release` and
# `workflow_dispatch` triggers cover manually created releases and re-runs.
