gs-details-page: Show version of the installed/offered application
Coming from a downstream bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=2000270
The Version
doesn't show the version being installed, or being offered by the source, when it's not reflected in the app stream data. An example is on the Fedora libreoffice-writer, which should the version from the appdata, which does not match the installed version.
