[gtkmm-documentation] Change git.gnome.org to gitlab.gnome.org

[Kjell Ahlstedt <kjellahl src gnome org>]

commit 59e6ea9504f3e79d937fe364d82bb06bd2c10b24
Author: Kjell Ahlstedt <kjellahlstedt gmail com>
Date:   Tue Jan 7 15:21:09 2020 +0100

    Change git.gnome.org to gitlab.gnome.org
    
    * docs/tutorial/C/index-in.docbook: Change URLs.
    * docs/tutorial/insert_example_code.pl: Don't add url_examples_branchsuffix.
    The branch is not a suffix in gitlab, it's included in url_examples_base.
