feat: add live example index pages for primitive components PTL-0

[matteematt]

• Change the index pages for forms, presentation, and interaction to have cards with live examples
• Add some react hooks to help with the index pages
• Updates the css around the sidebar size, so it shrinks a bit when there is a small screen
• Changes some components to render less information (or different styling) when the live example is part of the index
• Changes some components to know when they're squished small and to change what they're rendering

nit: indentation

Tested and all is looking great. Only little nitpick I have is if you clicking an image within a card doesn't redirect. You have to click anywhere inside the card but not the image.

@matteematt suggest we look at the clicking on image issue in a separate PR
