Old jekyll requirement

[makew0rld]

Is this requirement still needed? This plugin won't work with the latest Jekyll because of this line.

You can specify the exact version in your Gemfile like this:

gem 'jekyll', '4.2.0'

Or install a specific version from the command line:

gem install jekyll -v 4.2.0

Yes, I know. But ideally this plugin would be updated so that later versions of Jekyll could be used.
