There are 2 possible failures of toHaveScreenshot

show diff between Actual/Previous and have Expected as a separate
screenshot.

Closes https://github.com/microsoft/playwright/issues/23964.
Trace snapshots are a best-effort snapshots of the browser DOM, but we
can't guarantee them to be exactly what the browser showed. One example
of this is `canvas` elements, where you just can't see their contents.
That makes snapshots useful, but not perfect.
For those cases where the snapshot doesn't show everything, this PR
introduces a new setting to show a screenshot instead. You won't be able
to scroll or inspect the DOM or select a locator anymore. But if the
snapshot was missing something, or displaying something wrong, you can
now check the screenshot instead.
Closes https://github.com/microsoft/playwright/issues/32159. I
originally set out to enable Strict Mode for our React UI, but found a
way better thing: Enabling the lint rules we had already installed!
`eslint-plugin-react` is already in of our `package.json`, and this PR
enables it and fixes some of the reported issues. Most of them are
around the `key` prop which is mostly about performance, but there's
also fixes for misspelled `data-testid` props.

When keyboarding through the action view, the UI continues showing the
hovered action. This makes keyboard nav hard to use.
The fix is to reset the higlighted action on keyboard navigation. This
is what we do when the mouse pointer leaves an action, and what I think
is reasonable.
