### Summary by OpenAI

Release Notes:

- New Feature: Added a GitHub Actions workflow file named
`versioning.yml` that triggers on release events and runs a job to tag
the latest commit using an external action.
- Chore: Updated the version of `fluxninja/openai-pr-reviewer` used in
the workflow from `main` to `latest`.

> "A new workflow has arrived,
> To tag commits with ease and pride.
> With updated dependencies in tow,
> Our codebase is ready to grow."
