Fix-up pipeline from failed beachball publish

[rajsite]

Pull Request

🤨 Rationale

The beachball publish command failed do to a recent change in the invoke-publish scripts.

👩‍💻 Implementation

• Fix-up the package files to align with the expected partial published package versions (so the next attempted publish can release correctly)
• Fix the invoke-publish command
• Split out the setup code in the invoke-publish commands into a separate invoke-publish:setup command to make them easier to test locally
• Add docs for how to recover from failed / partial beachball publishes

🧪 Testing

Ran the invoke-publish:setup commands locally, otherwise relying on CI.

✅ Checklist

• [x] I have updated the project documentation to reflect my changes or determined no changes are needed. Added docs for recovering from failed beachball publishes.
