feat(docker): Add multi-platform support for Docker build

+# Pin the reusable workflow to a commit until the PR is merged; then prefer a semver tag.
+# Ref must be a literal (not env). Update SHA when rebasing the shared-workflow PR.
+# Inner steps in docker-build-push.yml use FuelLabs/github-actions composites; they may
+# still reference @master — if something diverges during testing, align those refs in the PR.
+#
+# Do not use strategy.matrix on the same job as workflow_call + job-level `if` with
+# matrix.* — job `if` is evaluated before matrix expansion for reusable workflows.
+# Add one job per package with an explicit `if` (package name literal) instead.
