Simplify Resource type descriptive note

[mark-dce]

STORY
As a repository owner, I would like the resource type note to be shorter, so that my form isn't as long...

Pre-defined categories to describe the type of content being uploaded, such as "article" or "dataset." More than one type may be selected.

ACCEPTANCE

• The descriptive test under resource type on the deposit form reads: "More than one type may be selected."
