.asciidoctorconfig files are no longer honored

With Eclipse 2025-06 (4.36.0) and Version 3.1.2 of the Asciidoctor Editor plugin, I'm facing the issue that `.asciidoctorconfig` files no longer have any effect. Neither the Asciidoctor console nor the Eclipse Error Log offer any clue. It did work as expected in earlier versions of Eclipse and the plugin, though unfortunately I can't tell which versions those were.
