[Nick Wellnhofer <nwellnhof src gnome org>]

commit 967534504827fa79d39903ab0f94a7583a3925b9
Author: Mattia Rizzolo <mattia mapreri org>
Date:   Thu Jul 29 12:14:03 2021 +0200

    Correctly install the HTML examples into their subdirectory.
    
    Previous to this commit, the examples where installed haphazardly within
    all the other html documents, also overwriting index.html, for example.
