fix(next): supports root document view overrides as separate from default edit view (#7673)

## Description

We've since lost the ability to override the document view at the
root-level. This was a feature that made it possible to override _the
entire document routing/view structure_, including the document
header/tabs and all nested routes within, i.e. the API route/view, the
Live Preview route/view, etc. This is distinct from the "default" edit
view, which _only_ targets the component rendered within the "edit" tab.
This regression was introduced when types were simplified down to better
support "component paths" here: #7620. The `default` key was incorrectly
used as the "root" view override. To continue to support stricter types
_and_ root view overrides, a new `root` key has been added to the
`views` config.

You were previously able to do this:

```tsx
import { MyComponent } from './MyComponent.js'

export const MyCollection = {
  // ...
  admin: {
    views: {
      Edit: MyComponent
    }
  }
}
```

This is now done like this:

```tsx
export const MyCollection = {
  // ...
  admin: {
    views: {
      edit: {
        root: {
          Component: './path-to-my-component.js'
        }
      }
    }
  }
}
```

Some of the documentation was also incorrect according to the new
component paths API.
