Describe the bug

Setting the "includeExplanation" option to true on codeToHtml works as expected but typescript does not recognize it as a valid property. This only causes an error if you use an object literal in the argument, for example:

// typescript error:
// error TS2353: Object literal may only specify known properties, and 'includeExplanation' 
// does not exist in type 'CodeToHastOptions<BundledLanguage, BundledTheme>'
shiki.codeToHtml(code, {
  lang: 'md',
  includeExplanation: true
});

Current workaround, should anyone see this thread before a fix exists, it to simply typecast:

shiki.codeToHtml(code, {
  lang: 'md',
  includeExplanation: true
} as CodeToHastOptions);

I'm unable to provide a patch at this time but the fix is straightforward.
