as in Openscapes/quarto-website-tutorial#37. Dark mode was not working, so remove it.

@k-doering-NOAA How is light/dark not working? Seems to work for me. the theme-dark.scss file is in the repo

Sorry, I should have been more clear!

The code blocks don't show up when toggling to dark mode.

e.g., see the software and code section and toggle between dark and light mode: https://nmfs-opensci.github.io/ResourceBook/content/licenses_gov.html#software-and-code

I tried to add the following to theme-dark.scss, but it didn't fix it, so instead went with the solution that openscapes identified.

$code-block-bg: #181818;
$code-block-color: white;
