Support for antora

[jcralbino]

Hello
Thanks for releasing this tool. It does provide benefits when entering through asciidoc environment to be able to see the information as presented by AsciidocFx

I wanted to know if you have considered providing also some improvements to make it easier to preview antora projects, as we have seen in asciidoctor-vscode

Best Regards

Here is a reference
To some merges done in viscose extension related to this

asciidoctor/asciidoctor-vscode#434

I understand that making it 100% antora aware is daunting , so we may start only by allowing the image preview to be working ?
