Hugo: Fix git bug when installing a repo with a theme

بِسْمِ ٱللَّٰهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ

If you have tried installing a repo from GitHub/GitLab or any other git host that is a Hugo project with a theme, a bug may appear that has the following error:

WARN 2022/05/22 found no layout file for "HTML" for kind "home": You should create a template file which matches Hugo Layouts Lookup Rules for this combination.
WARN 2022/05/22 found no layout file for "HTML" for kind "taxonomy": You should create a template file which matches Hugo Layouts Lookup Rules for this combination.
WARN 2022/05/22 found no layout file for "HTML" for kind "taxonomy": You should create a template file which matches Hugo Layouts Lookup Rules for this combination.

This bug can be reproduced by doing the following:

git clone https://github.com/colmjude/hugo-data-template-tutorial

And then trying to run the project using Hugo:

cd hugo-data-template-tutorial

hugo server -D

This bug will cause blank pages to appear when running the server, as the theme is missing from the project.

This can be fixed by doing the following:

git rm --cached themes/ananke
git submodule add https://github.com/theNewDynamic/gohugo-theme-ananke.git themes/ananke

Or alternatively by using the recurse-submodules command when cloning:

git clone --recurse-submodules https://github.com/colmjude/hugo-data-template-tutorial
