This splits all of the current job and role documentation into
files by subject area so that jobs and roles are easier for users to
find.
This will require that any future new jobs or roles add a line to the
appropriate area of the documentation, since that can no longer be
done automatically. A linter check is added to ensure that every
job and role continue to be documented.
After this refactor, we can begin to enhance the documentation pages
so that they include narrative documentation and subsections.
