Append an "Aria snapshot:" section to failure messages from
toBeTruthy / toMatchText / toEqual matchers so it is easier to
diagnose what was actually on the page when the assertion failed:
- containment matchers (toHaveText, toContainText) print the full
subtree of the matched element;
- property matchers (toBeChecked, toHaveAttribute, toHaveRole,
toHaveValue, toHaveCSS, ...) print just the element line (depth 1);
- when the locator did not resolve to an element, or resolved to a
hidden one, fall back to a full-page snapshot from document.body;
- to.have.count, *.array and to.match.aria assertions are excluded.
The protocol shape changes from `received: SerializedValue` to
`received: { value?, ariaSnapshot? }`.
