    docs/sphinx: Refresh config for newer Sphinx
    
    Sphinx 5.0 and newer objects to language = None.  Switch to 'en'.
    
    Also update the copyright year.  Use %Y to avoid this problem in the future,
    and provide compatibility for versions of Sphinx prior to 8.1 which don't
    support the syntax.
