Description of the need

Entity Reference was added to Backdrop with version 1.23, but it's not enabled by default. It should be easier to find and use this module.

Proposed solution

Like all other field modules of Backdrop core, Entity Reference should be enabled in new installations.

Draft of feature description for Press Release (1 paragraph at most)

Backdrop now not only includes Entity Reference but enables it out of the box ;-)
