New module in the World/ GitLab group: Amtk

[Sébastien Wilmet <swilmet gnome org>]

Hi,

Amtk used to be part of the GNOME/ GitLab group, then it was archived,
it's now again alive, in World/:

https://gitlab.gnome.org/World/amtk

If all goes well, amtk will be a dependency of gedit. So when
translating gedit, if you see some untranslated strings in the UI, it
can come from Amtk ;-)

Thanks!
Best regards,
Sébastien
