Update asciidoctor requirement from 1.5.6.2 to 2.0.10

[dependabot]

Updates the requirements on asciidoctor to permit the latest version.

Release notes

Sourced from asciidoctor's releases.

v2.0.10

Summary

This is a minor bug fix release that patches two regression, one when using the header_footer option with Asciidoctor.convert_file and one when the icons attribute is set to image. It also addresses a minor issue in the default stylesheet with excerpt blocks and passes a consistent set of arguments to SyntaxHighlighter#docinfo. The Japanese version of the README has been brought up to date thanks to @soishino and @wotsushi.

Distributions

We should apply the Asciidoctor migration cheat sheet before upgrading to 2.0.10:

@jnavila I think we should close this issue, so that nobody can get confused between our migration and the automated Dependabot one.
