transform, useForSnippets and preferForRegexpMatch can all be optional.

⚡️ What's your motivation?

I'm using this library separately and found this type issue.

♻️ Anything particular you want feedback on?

If type can be null, can it be undefined and optional too?

thx. How do I update the change log? Do I just add an entry under the Unreleased section, or I should use some tools like the polyglot-release or changelog mentioned in https://github.com/cucumber/.github/blob/main/RELEASING.md?
