Suggestion: add a reference link

It would be super helpful if each feature page linked to a developer resource page or guide, where developers could learn about the feature in more lay terms than w3c specification language. Fore example, linking `light-dark()` (https://webstatus.dev/features/light-dark), to a resource such as https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/light-dark would be super useful.

Thank you for your consideration.
