Docs are not building

Problem

Recently we upgraded to Sphinx v7 because the docs had stopped building.

However Jinja needs to also be upgraded, and there are a few errors being thrown when building the docs.

Solution

• [x] Remove the explicit dependency for jinja in docs/requirements.txt, so that sphinx handles the version it needs.
• [x] Update custom styling path to use new setting variable in source/conf.py
• [x] Fix parsing errors
