[Fixed] Mark Page.Accessibility.snapshot/2 as @deprecated

According to Playwright.dev, accessibility testing should be executed with
separate, spacialized libraries. The Playwright implementation is deprecated.

This change also removes a failing test, in keeping with the matching removal
from Playwright proper. It appears that the browser behavior was considered to
be too inconsistent.
