[LyX/master] Export ' (straight) as ’ (curly) in DocBook

[Thibaut Cuvelier]

commit d4095dc0e65d292c3ae0772a429d1db662573f14
Author: Thibaut Cuvelier <tcuvel...@lyx.org>
Date:   Fri Dec 9 01:25:34 2022 +0100

    Export ' (straight) as ’ (curly) in DocBook
    
    This is similar to what LaTeX does in its output.
    
    See the (long) discussion in ticket #11244. Port of ad3e6c69b2ce for 
DocBook.
    
    This patch requires delaying entire strings instead of just characters, so 
that the DocBook code path can be as similar to the XHTML one as possible.
