Make Add content/media default publishing option descriptions consistent

Problem/Motivation

When adding a new Content type (/admin/structure/types/add), the "Publishing options" for the "Published" and "Create new revision" options are as follows:

Published
Description: null

Create new revision
Description: Users with sufficient access rights will be able to override these options.

When adding a new Media type (/admin/structure/media/add), the "Publishing options" for the "Published" and "Create new revision" options are as follows:

Published
Description: Media will be automatically published when created. 

Create new revision
Description: Automatically create new revisions. Users with the "Administer media" permission will be able to override this option.
