Additionally, the emacs 26.1 release does not have the emacs-module.h too:

So this might be a change in 26.1 . I cant update my example for 26.1 just
yet. So hopefully someone else knows.

The simplest solution is check the 26.1 tarball and see if it exists there,
and just manually copy and and it to your projects VC. this requires
copyright compliance. It's really the only reason I used the wget method
anyway.
