Linting error for all pull request automated testing

Describe the issue/behavior that seems buggy

When running any automated PR tests or npm run lint, an error is generated:

<dir>/highlight.js/tools/lib/makestuff.js
  8:19  error  Parsing error: Unexpected token import

This makes all pull requests fail testing.

Sample Code or Instructions to Reproduce

npm run lint or open a pull request

Error is in line to of this snippet:

async function clean(directory) {
  let del = await import('del');
  del.deleteSync([directory]);
  fs.mkdirSync(directory, { recursive: true });
}

Expected behavior All tests should pass

Additional context

There is an issue in the eslint repo with the response:

When using the default parser and sourceType: "module", the word import becomes a keyword token that can only be used in import declarations.
