Pull Request Overview

This PR enhances the scope markdown generator by registering two new document scopes as sensitive and suggesting alternative non-sensitive scopes that share the same prefix.

• Adds https://www.googleapis.com/auth/documents and .../documents.readonly to SENSITIVE_SCOPES.
• Implements suggestion logic in getScopeMarkdown to list non-sensitive scopes with the full shared prefix.
• Introduces a helper getSharedPrefix function.
