Makes it so the index looks more like a cheatsheet, condensing information instead of making long lists that require lots of scrolling to explore. Additionally, the happy path for each validator was also added, providing a quick reference use for comparison. The direct markdown links were replaced by titled markdown references, offering mouse-over tooltips over links that display the validator one-line description. To ensure a proper source of truth for these new index goodies, the AssertionMessageLinter was modified to verify that the first assertion in each doc is a single-line validator that passes (a happy path), further making our documentation conventions more solid.
