Removes the currently logged-in member from the site community and sets their profile to private.
The makeProfilePrivate() function returns a Promise that resolves to a member object
when the member's profile privacy is updated.
When a member's profile is private, they do not have access to the site's Members Area features, and their profile is hidden from other members and site visitors.
