Low Text Contrast in Dark Mode of Scancode Documentation

[alok1304]

When I was going through the Scancode documentation, I noticed that text within black boxes was difficult to read due to low contrast in dark mode. However, the same text is clear and readable in light mode.

I also provide the link of that and also attach screenshot.

And this text is fine on light mode
