check-sync.yml

# This repository contains intentionally duplicated copies of files:
# - Workflow template copies under workflow-templates/dependabot/workflow-template-copies used for Dependabot checks.
# - Workflow template copies in .github/workflows used for this repository's own CI system.
# - Assets for the workflow templates used in this repository.
#
# This workflow checks that the copies are in sync.
# If the workflow fails, run `task dependabot:sync` and commit.
