fix: CJS build issue fix

Without this anything that uses ember-cli-addon-docs then explodes with:

```
require() of ES Module /Users/michal/ember/ember-intl/node_modules/.pnpm/@handlebars+parser@file+..+handlebars-parser/node_modules/@handlebars/parser/dist/cjs/index.js not supported.
Instead change the require of index.js in null to a dynamic import() which is available in all CommonJS modules.
```
