[gtksourceview] docs: add page IDs

[Sébastien Wilmet <swilmet src gnome org>]

commit 1143d995c394f998a8f10e42ff6816968d6655a1
Author: Sébastien Wilmet <swilmet gnome org>

    docs: add page IDs
    
    To have more future-proof links, instead of "pt01.html", "pt02.html"
    etc.
    
    Rename also Other section -> Misc. I think Misc is a better name, and is
    consistent with Tepl.
