fix: clarify updatecli configuration in dependency review example

## Summary
This fixes a workflow configuration trap in the Dependency Review examples.

- Updated the Updatecli guidance comment to explicitly tell users to uncomment the `with:` block before setting `allowed-bot-users`.
- Regenerated the compiled workflow so `.github/workflows/trigger-dependency-review.yml` matches the source template.

## Why
Issue #1148 reported that users could reasonably uncomment only `allowed-bot-users`, which places it at the job top-level and produces an invalid workflow.

Closes #1148.
