Jekyll version plugin

Recently I added a Generator section to the about page with minimal information about how this page was generated.
As part of this it now also shows the version of the Jekyll software that was used to generate everything.

Surprisingly there seems to be no built-in way to get the version as a template tag.
Thus I wrote this mini-plugin to provide such a {% jekyll_version %} tag that can be used to get the version of Jekyll while it is processing the pages.

To use it with your own Jekyll, simply store the below code in a _plugins/jekyll_version_plugin.rb file.

# frozen_string_literal: true
module Jekyll
  class VersionTag < Liquid::Tag
    def render(context)

Liquid::Template.register_tag("jekyll_version", Jekyll::VersionTag)
