highlight.js 3rd party plugin error: Cannot read properties of undefined

**Highlight.js version:** 11.6.0

**Node version:** v18.12.0

**npm version:** 8.19.12

When I provide a plugin with the following code to highlightjs (full code is at [github](https://github.com/razetime/highlightjs-bqn/commit/2dae3376e71ed9c19fd7a98abf4f2690d927fd48)):
```
/*
Language: BQN
Requires:
Author: Raghu Ranganathan <rraghu.11502@gmail.com>
Contributors: 
Description: BQN array language definitions
Website: https://mlochbaum.github.io/BQN
*/
export default function(hljs) {
  return {
 name: "BQN",
    unicodeRegex: true,
    keywords: '•BQN •ReBQN •primitives', // only primitive functions included.
    contains: [
    {
      scope: 'string',
      begin: '"', end: '"'
    }
  }
```

I get the following error during build:
```
$ node tools/build.js -t node
Starting build.
Finished build.
Writing styles.
/home/razetime/Documents/Code/gen/highlight.js/tools/build_node.js:184
  const common = languages.filter(l => l.categories.includes("common"));
                                         ^

    at async doTarget (/home/razetime/Documents/Code/gen/highlight.js/tools/build.js:90:3)

Node.js v18.12.0
```

What is causing this error?
