Dark mode settings used to render code in light mode

[nmaguiar]

Description
When using ojob.io/httpServers/EasyHTTPd, with MD_DARKMODE set to auto, any markdown rendering with code will apply dark mode colors.

To Reproduce
Steps to reproduce the behavior:

1. Execute: OAF_FLAGS="(MD_DARKMODE: 'auto')" ojob ojob.io/httpServers/EasyHTTPd port=8888 path=/some/path uri=/f
2. Browse to http://127.0.0.1:8888/f and try to find a YAML file to display.
3. Switch your OS dark mode on and off.
4. See the colors in light mode not being applied correctly,

Expected behavior
In light mode it should have the same behaviour as with MD_DARKMODE=‘false’
