Mindmap stops rendering when page has a Codeblock with unknown language

[ggarcia24]

Hello,

First of all, thank you very much for creating this plugin is has been really usefull 😄. I think I've found an issue with code blocks:

I'm currently having a page that looks like the following:

# H1

Text

## H2

- This is something

## H2

- This is something

## H2

- This is something

If I add a code block with JSON language in the file the Mindmap window stops rendering

# H1

Text 

```json
{
   "a": "b"
}
``` # 
... (rest of the file)

The following error appears in the console:

index.js:44 Uncaught (in promise) TypeError: require.resolve is not a function
    at eval (eval at <anonymous> (app.js:1), <anonymous>:27101:32)

This is really weird because obsidian is rendering correctly the code block (highlighting with JSON syntax) but Mindmap cannot, it needs to have a js lang or no lang at all

I have the same problem, if I copy the markdown to the markmap live demo it works as expected but in the obsidian plugin nothing is shown.

Probably the same issue as #25
