I used shell as the docs appear to be using HighlightJS, and the documentation says that shelland console are both aliases for the same thing. https://highlightjs.readthedocs.io/en/latest/supported-languages.html

Having never used honkit I'm not completely sure if there's any preprocessing that would get in the way and complicate this situation though... but I based the PR on the HighlightJS docs since the honkit code for syntax highlighting (https://github.com/honkit/honkit/tree/d058ddfcd0837af110c9f2d49f612bc0b75390b4/packages/%40honkit/honkit-plugin-highlight) looks like its just a wrapper around HighlightJS.

Edit: Would you still like the shell swapped for console even though they should be functional equivalent aliases @ekohl ?
