Better dark colour scheme for code samples

[sheeit]

Describe the change you'd like

Add a proper dark colour scheme for code samples. Currently, code listings (syntax highlighted code examples on Wikipedia) simply don't look as good as with this style off.

Additional context
Here's an example of what it looks like:

Notice that most of the colours are not changed in dark mode, and don't look as good with a dark theme.

The blue for instance, is almost invisible.

Thanks for reaching out to us.

I can make the blue more visible, but as for making new complete theme, not a sausage Im afraid. =)
