Infographics at /drupal-8.0/* are out-of-date

Problem/Motivation

There are some infographics which are downloadable by clicking a banner on the page at:

• https://www.drupal.org/drupal-8.0/cios
• https://www.drupal.org/drupal-8.0/content-admins
• https://www.drupal.org/drupal-8.0/developers
• https://www.drupal.org/drupal-8.0/marketers
• https://www.drupal.org/drupal-8.0/sitebuilders
• https://www.drupal.org/drupal-8.0/themers

... which could use some updating. Some known issues...

• on the bottom of the first page of every infographic, there is a "THE DRUPAL 8 TIMELINE" section which states that we're in API Freeze, not Betas.
• the infographic for developers says that Drupal 8 uses Assetic, which has been postponed to 8.1.x at least.

Proposed resolution

Update the infographics.

Remaining tasks

• Find the person with the originals (Jsaylor?).
