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

Release notes

Sourced from asciidoctor-pdf's releases.

v2.1.4

This is a patch release in the 2.1.x release line that includes backports from the 2.2.x release line. It fixes several issues that have been hiding in the shadows for a long time and enhances the warning message for truncated table cells.

If the alt text for a block image, video, or audio exceeds the width of the content area, the text will wrap to the next line instead of being advanced to the next page. This fix prevents a fixed width table cell from breaching the height of the page. In the event that a table cell does exceed the height of a page, and the sourcemap is enabled, the warning message will include the source location of the cell. The converter will no longer suggest enabling the allow-uri-read attribute if an image target contains a colon, but is not a URL. If a custom role contains the text-transform property, that transform will be applied the value of an attribute reference. Previously, the transform would be applied before attribute references are resolved.
