[epiphany] Update help index and introduction

[Ekaterina Gerasimova <egerasimov src gnome org>]

commit 26996e9f803ba2b95a9cdcbfff300e45e8ef55e0

    Update help index and introduction
    
    Index <desc> is now used as the project description on h.g.o/users, so
    should contain something of interest to users and "epiphany" because
    "web" is a poor search term on the internet.
    
    Using epiphany will not make the web any more nicer a place. Would be
    good to mention something about privacy as it's a moderately big
    feature. Can't think of a nice way to fit it in right now.
    
    <p> inside <media> are alt text, used to describe the image and double
    up as instructions for retaking the screenshot.
