🛠 Tooling: shenanigans-manager version command

[JoshuaKGoldberg]

Tooling Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Overview

yarn lerna version isn't enough to bump versions of everything, because there are setup/**/package*.json files that include references to other packages. shenanigans-manager should have a version command added that acts as a wrapper+coordinator around npm version and/or yarn lerna version.

Additional Info

I'm wondering if it should have a publish command too...
