Remove the default loading of `nord` theme when `getHighlighter` about shiki HOT 3 CLOSED

Give that this would be a massive breaking change, it probably shouldn't happen this way unless it ends up in the 1.0 changes in #424 and is very well documented

Perhaps passing null could be accepted as the theme and have this behavior instead

I agree that removing the logic here directly may produce incompatible changes, although the documentation doesn't explicitly mention that the default theme will be loaded, it may be the default behavior when the user relies on not passing theme.

If, as you say, we remove the loading of the default theme when the user is shown using theme: null or themes: null, would this be acceptable as a patch version of v0.14?

Sure, allowing specifically for null is something I'd be OK with merging (as long as that's documented in the jsdoc)
