Fix phpstand next major

Hi @yuvania,

Thanks for opening this issue.

I've been working on issues for this module today, and the failure for phpstan next major should now be fixed by this issue 📌 Update renderPlain() to RendererInterface::renderInIsolation() as reported by PHPStan Fixed .

If you still see an issue, or if you have a merge request for review, I'll be happy to look at it.

As all test and code quality checks are now passing, I'm going to consider this a duplicate issue and mark closed.

Thanks for opening. Sorry it happened to be in the middle of a clean-up.
