Regardless of what dot code I put within a tag, the render is the same default failure image

This happens regardless of whether I put /usr/bin/dot into the configuration manager, or leave it blank.

I got it working for release 2025-05-14a using the changes mentioned in #17.
I also had to add "use dokuwiki\HTTP\DokuHTTPClient;" in syntax.php
