Associate people as authors

User story

As a content editor,
when I post an article or blog
I want to add an author or authors so those posts can be associated with "people" on the site.

Background

Proposed solution

• Add an entity reference field that will link to people content.
• Allow multiple values for multiple authors.
• Update displays.
• The field storage has already been added to the People feature.

Remaining work

• Eventually, we can enhance our people content type so that a list of article and blog posts by a person appear on their bio page.
