IRuleMetadata::options should have a real type

[JoshuaKGoldberg]

It's any now. A quick aka.ms/types search isn't showing any results for a standard type; should one be made?

💀 It's time! 💀

TSLint is being deprecated and no longer accepting pull requests for major new changes or features. See #4534. 😱

If you'd like to see this change implemented, you have two choices:

• Recommended: Check if this is available in ESLint + typescript-eslint ✅
• Not Recommended: Fork TSLint locally 🤷‍♂️

👋 It was a pleasure open sourcing with you!
