dependabot.yml

# Automatically save updated `pnpm-lock.yaml` file for dependabot PRs.
# This is necessary because dependabot doesn't support pnpm yet:
# https://github.com/dependabot/dependabot-core/issues/1736
#
# Note: We use the `pull_request_target` event due to GitHub security measures.
#       It is important to ensure we don't execute any untrusted PR code in this context.
