Suggest using target language syntax highlighting in QLDoc

Are there any common places where users will view QLDoc where target-language highlighting isn't supported, and the target-language specifier is just cluttering things? I know that VSCode supports highlighting. Does the translation to whatever our online help format is handle this? Does it at least strip out the language specifier when it formats as HTML?

As for viewing on GitHub itself, let's try and see:

int main(int argc, const char* const* argv) {
  return 0;
}

I tested with this QLDoc (which has been around for 9 months), and it renders fine in our help pages, as well as in the LGTM query console (hover over the unifiable predicate).
