Remove "User restriction" and "Restriction" from the titles used in form elements for the edit form

Problem/Motivation

The current title for the label form element in the form to edit or create a user restriction is User restriction name, but it is not necessary to say it is the name is for the user restriction, since it used in a form to edit or create a user restriction.
Similarly, it is not necessary to use Restriction type as title.

Proposed resolution

Remove User restriction and Restriction from those titles.
