# Version Bump Workflow for .pre-commit-config.yaml
#
# This workflow runs on a cron schedule and checks for updates to the
# .pre-commit-config.yaml file. If updates are found, the workflow
# commits the changes to the next branch and pushes the changes to GitHub.
#
# This is a workaround for the fact that the pre-commit autoupdate command
# is not supported by Dependabot.
