Update images in the docs

A PWA score does not display, even though 9/11 items under Progressive Web App tests are positive. Scores display for all other tests.

@chrisdeveloperit the PWA category has sections to complete that represent the different aspects of being a PWA, the numeric score is not really meaningful and is never displayed to the user. Upon completion of all 11 items it changes to a checkmark.

Thank you @patrickhulce . The Lighthouse Scoring Guide lead our team to think that our Lighthouse Report should look like the image displayed in their documentation. https://developers.google.com/web/tools/lighthouse/v3/scoring

Ah thanks for the explanation @chrisdeveloperit! That is the scoring guide for v3 which used a numeric system for PWA. From v4 onward (on v5.5.0 currently), the PWA scoring system is the one you see in the pdf you filed 👍

We should update all these stale images.
