textproc/ruby-asciidoctor: update to 2.0.20

2.0.19 (2023-05-17)

Development on Asciidoctor 2.1 has been on pause while we focus on
progressing the AsciiDoc Language Specification.  In the meantime, we
extracted some of the minor improvements and bug fixes from main and put
them into this patch release in the 2.0.x release line.

The most impactful fix is a switch from recursion to a while loop to prevent
a stack limit error when looking for the next line to process.  Those using
JRuby will appreciate that fact that a uri:classloader: prefix is treated as
an absolute path rather than a URL, which will allow those paths to be read
correctly and avoid misleading security warnings.

A few refinements where made to how the AsciiDoc source is parsed.  First,
constrained passthroughs inside a monospace span are now always processed as
expected.  When parsing a dlist, a nested list that starts with at least one
block attribute line is now attached correctly.  The partintro block is now
generated consistently, despite how it's defined in the AsciiDoc source.
Numeric character references are passed over when searching for the URL
fragment in the xref target.  An inline ref is cataloged even if the
resolved reftext is empty.  An include target may not start or end with a
space (to distinguish it from a dlist entry).  Finally, square brackets are
not swallowed when parsing an escaped URL macro.

Several improvements have been made when converting to man pages.  When
generating DocBook, the root <reftext> tag is correctly enclosed in an
<article> tag and reftext substitutions are applied to the value of the
mantitle attribute.  When converting to the man page format, the alt text of
a block image is processed correctly (i.e., "manified").  In the HTML
output, a monospace span in a section title is not converted to uppercase.

The default stylesheet has been updated so that the margin on the first and
last child of a sidebar is collapsed correctly and so the font size of a
term in a horizontal list matches the font size of a term in a regular
dlist.

The code has been updated to be compatible with recent software releases,
including Ruby 3.2, Haml 6, and Rouge 4.1.
