When setting a Project as private, show which repos are public or contain a public issue tracker/wiki

Problem Definition

When a project contains public repositories and/or a public issue tracker/wiki in its repos, the following message appears in the Project Settings and the user is prevented from making the project private:

The message above doesn't specify which are the public repos or the repos containing a public issue tracker/wiki, so an admin will have to check them one by one.

Suggested Solution

Include in this page (or possibly in a message shown when the user attempts to make the project private) a list the public repos or the repos containing a public issue tracker/wiki.

Why this is important

For projects containing a large number of repos, it can be time consuming to check all repo/issue tracker/wiki settings one by one. Showing a list will allow the admin to immediately fix (make private) the ones needed.
