[dependabot]

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

Release notes

Sourced from asciidoctor-pdf's releases.

v2.1.3

This is a patch release in the 2.1.x release line that backports fixes from the 2.2.x release line. It addresses a few minor layout bugs and one hairy bug that was staring us straight in the face.

If the value of either the page-numbering-start-at or running-content-start-at theme key is set to 1, the converter was treating that value as 1 instead of 2. Now it will interpret it as entered. If you import a page using the image macro, the converter will restore the margin and column layout on the page that follows it. Various border-color keys now accept the value transparent rather than causing the converter to crash.
