    app: update/fix the About's authors.xsl.
    
    I realized the "recent-contributor" template was checking
    `last-active >=2 and minor version >= 8`. Because of the second part of
    this test, anyone with a last a last-active value of 3.0 was ironically
    not included as recent contributors!
    
    Meanwhile, I am bumping the definition of recent as 2.10 and over
    (rather than 2.8 and over), for GIMP 3.0 release. Last thing, I am now
    sorting by descending last-active (so contributors in GIMP 3.0 are shown
    first).
