Use git submodule instead of using ssh to clone metanorma.com

It is simpler to use git submodule for project site instead of writing a script to clone, and much easier to make production deployment work too.

I’m not sure I see a problem due to which production deployments don’t “work” with cloning. What submodules could indeed help with is reducing build time and eliminating some of the build logic. The choice to go with cloning was made to avoid the need to commit changes each time a subproject changes, since build time is considered less important than convenience of maintaining up-to-date docs.

It doesn’t belong in this project but it’s something to consider, so I filed a corresponding issue against the corresponding plugin gem (riboseinc/jekyll-theme-open-project-helpers#1). Thank you!
