Pygments styles used for syntax highlighting.
These are based on the Sphinx style (see
https://github.com/sphinx-doc/sphinx/blob/master/sphinx/pygments_styles.py)
for light mode and the Friendly style for dark mode.
The styles here have been adjusted so that they are WCAG AA compatible. The
tool at https://github.com/mpchadwick/pygments-high-contrast-stylesheets was
used to identify colors that should be adjusted.
