Ensure the theme detects templates and add one for the frontpage.

[laceysanderson]

This PR ensures that

• this theme is detecting templates
• adds the default template for the page from olivero
• adds a specific template for the frontpage based on the original page template
• adds a specific css library/file for themeing of the frontpage
• extends the docker environment for better theme development (sets twig debugging to true).

Testing

Create a new docker on this branch

docker build --build-arg drupalversion=10.2.x-dev --build-arg phpversion=8.3 --tag=trpcultivate-theme:4x ./
docker run --publish=80:80 -tid --name=theme4x --volume=`pwd`:/var/www/drupal/web/themes/trpcultivatetheme trpcultivate-theme:4x
docker exec theme4x service postgresql restart

You should now see the following on the front page:
