fix(feedback): Be consistent about whether screenshot should and can render (#11859)

This fixes the conditions for loading and rendering the screenshot
integration.... also improves the conditions for not rendering it if
we're on a mobile device.

- We should check the local`options.showScreenshot` instead of the
closed-over `showScreenshot` because the options might have changed for
this instance of the widget
- We should combine `options.showScreenshot` (the desire) with
`isScreenshotSupported()` (the possibility) to set the right expectation
