Add "Current Theme" under the Overview section

In my agency work, I frequently pull a site to local to work on the theme – or I have to pull up a site I already have locally for theme work. It would be super convenient to list the current theme under the “Overview” section, since that seems to go thematically with the WordPress version, site domain, multisite status, etc.

Here’s a mockup:

Ideally, I’d actually like to have that “Open Folder” button instead open the theme in my editor of choice – but I can live with just opening the folder.
