[Feature Request]: Add preview hovercards for internal links #1838
Description
Prerequisites
- I have searched existing issues to ensure this feature hasn't already been requested
- I have tested using the latest version of docs-builder
What problem are you trying to solve?

Proposed Solution

Examples and Research
