bwang 91e2e55a10 Simplify TOC spacing styles/logic by reusing the visible sticky header class
- Remove the 'vector-scrolled-below-table-of-contents' class, reducing the number of classes added with JS and simplifying the scrollObserver logic
- Move the 'vector-sticky-header-visible' class from the sticky header element to the body element. Hopefully, this is where other feature specific classes can go in the future
- This approach means the TOC will not need JS to update it's spacing when the sticky header is not enabled

{{!
Sticky header is hidden from screen readers because it contains duplicated content
that is already accessible to assistive tech via landmark roles, element type, and other navigation methods.
The interactive elements in the sticky header should have the `tabindex="-1"` attribute set to ensure
the header is also not tab accessible.
See https://dequeuniversity.com/rules/axe/4.1/aria-hidden-focus and https://phabricator.wikimedia.org/T290201
for more context.
