Distinguish packaging when two versions of the same app are installed

It would be nice to use the additional space in the list of search results to display the path of the currently highlighted entry. By only showing that information on hover/focus, this change would be minimally disruptive, while still providing relevant information.

For instance, I came across a situation where this would be useful, while attempting to try out the [recently released GIMP v2.10](https://www.gimp.org/release-notes/gimp-2.10.html), using the flatpak package they provide in https://www.gimp.org/downloads.

Here's a mock-up of how it could look like:


(Note the hover information showing up in the black tooltip, where the mouse cursor was placed.)
