Add a CSS rule to the default UI stylesheet for floating images
Images do not float properly in Antora 2.0, because the default UI stylesheet does not contain a matching rule for the role. Floating an image (see example below) worked in Antora 1.1. But in 2.0, an undesired alignment of the image and text is produced.

Dan commented, "we got rid of inline styles in the built-in HTML converter in Asciidoctor (well, at least most of them). So now we need a matching rule in the stylesheet for the role. This is a side effect of the upgrade to Asciidoctor.js 1.5.9. We never had a CSS rule in the default UI stylesheet, but the inline style from Asciidoctor 1.5.6 was hard coded."
