fix(cloudflare-pages): only allow 100 rules

[danielroe]

❓ Type of change

• 📖 Documentation (updates to the documentation or readme)
• 🐞 Bug fix (a non-breaking change that fixes an issue)
• 👌 Enhancement (improving an existing functionality like performance)
• ✨ New feature (a non-breaking change that adds functionality)
• ⚠️ Breaking change (fix or feature that would cause existing functionality to change)

📚 Description

CF only supports 100 rules, which includes the 'include' as well as the 'exclude' rule. Seems like this might have been lost in the refactor.

📝 Checklist

• I have linked an issue or discussion.
• I have updated the documentation accordingly.

Maybe we can minus the include length? (100-include)
