A. The main docs pages that were touched were:

1. Breadcrumbs
   a. I also removed all the aria-labels from the snippets because EuiBreadcrumbs has a default value so it's not absolutely necessary to provide a custom one. I confirmed with @myasonik (😭) that we only add custom ones in our examples because you can't have multiple on the same page with the same label. But I did add a callout about it.
2. Facets
3. Pagination
4. Tree view
5. Overflow scroll utility classes (added more a11y guidance)

B. Other related changes

1. EuiNotificationBadge

Closes #4992 by reducing the border-radius in Amsterdam theme

2. EuiPagination

Fixed the default active page to the actual first page. The activePage is actually 0 based index, but the default was set to 1 making it default to selecting page 2. 🤣

3. EuiTreeView

This is a component that controls the render of it's items through an object passed as a prop. While children was actually allowed via TS, it would error if you tried to pass any. So I set it to never allow children with children?: never;

4. EuiFacet

Updated the focus states in Amsterdam to match our established patter.

5. Changed doc's snippet code language from html to jsx

Mainly because nested objects made it very confused.

6. Reduced Playground code from 4 space indents to 2 spaces
