Fix gh-pages docs publication

Found an issue where enabling 'antora' sub-modules causes commits with
git-publish to be empty. For now simply remove antora module.
* CI:
  * Set write permissions
  * Update active branches
  * Use GH Actions token
* gh-pages Gradle script
  * Update active branches
  * Inject repo from CI env var
* Update .sdkmanrc to Java 11
* Some documents fixes

 Development for 4.x is against the link:https://github.com/asciidoctor/asciidoctor-gradle-plugin/tree/development-4.x[{github-branch}] branch.
 PRs are preferably taking against this branch.
 The 3.x series of the plugin is now in maintenance only mode.
