🛠 Tooling: Find or create an action that checks and fixes PR titles

### Bug Report Checklist

- [X] I have tried restarting my IDE and the issue persists.
- [X] I have pulled the latest `main` branch of the repository.
- [X] I have [searched for related issues](https://github.com/JoshuaKGoldberg/template-typescript-node-package/issues?q=is%3Aissue) and found none that matched my issue.

### Overview

I see a lot of PRs from first time / early contributors with titles like _`Fixes #...`_ or _`Feature: Do Some Thing`_. It would be nice if an action could post a comment saying _"hey, that title looks off, please make it adhere to (link to conventional spec)."_ And even better if the action can auto-apply those changes for people!
