Allow Library Items to be viewed by users who do not have edit permission

Problem/Motivation

We have a usecase where we want content editors to be able to access the canonical view of library items, but not be able to edit them.

This is because they can use library items in their content, but without being able to essentially preview the individual library items, it's hard for them to know which library items will work best with their content.

We have solved this using a route subscriber and custom entity access hook, but it would be great to have a permission included for this.
