Version number of installed app should be displayed in app page

• F-Droid version (in the About screen): 1.3.1

What did you do? (clear steps if possible)

Open an app description page of an installed app.

What did you expect to see?

I expect to find the version number of the installed version prominently displayed.

What did you see instead?

No version number is visible.

My workaround is to open the "versions" area and scan through it, looking for a version that is marked as installed. But sometimes my installed version is too old to be listed there (#1572 (closed)). In that case, I have to navigate to options->installed apps to find the installed version.
