Update asciidoctor requirement from 2.0.24 to 2.0.25

[dependabot]

Updates the requirements on asciidoctor to permit the latest version.

Release notes

Sourced from asciidoctor's releases.

v2.0.25

This is a patch release in the 2.0.x release line to fix bugs, address compatibility issues, and fix a minor annoyance.

If any custom block macros are registered, and the log level is debug, the processor will no longer log a false positive statement that certain lines contain an unknown block macro. When sectlinks is enabled, the link will not enclose any supplemental anchors on the section title, but only the text that follows.

In terms of AsciiDoc compliance, the trailing space after the reftext of an inline anchor defined using the inline anchor shorthand is now removed to allow the reftext to end with ].

And about that minor annoyance, the processor no longer freezes the processor instance of an extension, making it possible for the processor to use its own instance variables.

Distribution

• RubyGem (asciidoctor)

Asciidoctor is also packaged for Fedora, Debian, Ubuntu, Alpine Linux, OpenSUSE, and Homebrew. You can use the system's package manager to install the package named asciidoctor.
