vscode-extensions.asciidoctor.asciidoctor-vscode: 2.8.9 -> 3.4.2

About the postPatch snippet: The 'asciidoctor' program is no longer used
for previews, instead the extension uses
https://docs.asciidoctor.org/asciidoctor.js (which is bundled with the
extension). See upstream:
https://github.com/asciidoctor/asciidoctor-vscode/issues/443
("Remove Asciidoctor CLI option for preview rendering").
