Drupal `uses-responsize-images` unclear

The second half of the string https://github.com/GoogleChrome/lighthouse-stack-packs/blob/master/packs/drupal.js#L28 is unclear.

> Use the Responsive Image Styles when rendering image fields through view modes, views, or images uploaded through the WYSIWYG editor.',

Are there three ways of rendering an `image field`? (through a `view mode`, a `view`, or via upload from the WYSIWYG editor) Or is the WYSIWYG editor different and is uploading images directly instead of through fields?

This needs to be re-written by someone who knows what all these Drupal terms mean 😄

Start with packs/drupal.js at line 28 and review the wording of the uses-responsize-images string. Clarify the Drupal meanings of view modes, views, image fields, and WYSIWYG uploads before rewriting the sentence. Done means the string accurately distinguishes the relevant image-rendering paths.
