[gnome-software] details page: Show a different text for shell extensions prefs launching

[Kalev Lember <klember src gnome org>]

    details page: Show a different text for shell extensions prefs launching
    
    Instead of "Launch", show "Extension Settings" so that it's clear that
    the button is for opening the extension preferences.
    
    This reuses an existing string marked for translation and doesn't break
    the string freeze.
