[dependabot]

Updates the requirements on asciidoctor-pdf to permit the latest version.

Release notes

Sourced from asciidoctor-pdf's releases.

v2.1.1

This the first patch release in the 2.1.x release line. It's once again focused on the columnar layout, fixing one edge case and providing additional information for extensions. This release also addresses a crash when using CodeRay as the syntax highlighter and a code block uses a source language that CodeRay does not recognize.

An SVG that's shorter than the height of the current column will be placed in the correct column. The Extent for a decorated block provides access to the zero-based column where the block starts (from.column) and where the cursor was when the block was encountered (current.column). This information is used by the extended converter in the docs that demonstrates how to imprint the source language label on a code block.

The converter now draws a border around a phrase with a custom role using the base border color if the role defines a border width without a border color.
