Using [%step] on colist works the same as on ulist

[ibethus]

Hi,

This PR aims to modify the behavior of the step attribute on a callout block. I believe callouts should behave consistently with traditional lists when prefixed with this attribute.
This adjustment can enhance the presentation of code fragments, offering a more interactive experience.

Example :

[source, javascript]
----
let hello = "hello world"; <1>
console.log(hello); <2>
----
[%step]
<1> First line
<2> Second line

In the current implementation, only one fragment would be created. With this modification, individual fragments will be generated for each callout line, aligning with the intended behavior.

Code :
On the code side, I've only repositioned the fragment class definition in the colist template and included an example in the step.adoc file to illustrate this modification.

Cheers!

Thanks!
It would be great if you could create a release-5.2.adoc in https://github.com/asciidoctor/asciidoctor-reveal.js/blob/master/examples (similar to https://github.com/asciidoctor/asciidoctor-reveal.js/blob/master/examples/release-5.1.adoc).

Then, copy the HTML file in the public directory:

asciidoctor-reveal.js/Rakefile

Line 154 in cbe2ac7

FileUtils.cp 'examples/release-5.1.html', "#{PUBLIC_DIR}/release-5.1.html"

And add a link in:

asciidoctor-reveal.js/src/index.html

Line 24 in cbe2ac7

<li><a href="./release-5.1.html">Asciidoctor reveal.js 5.1</a></li>

That way, we can see the result using Netlify preview: https://deploy-preview-529--asciidoctor-revealjs-examples.netlify.app/

One test is failing because you've enabled :icons: font and update the template. You will need to update the expected result test/doctest/steps.html

Thanks for the feedback!

Documentation and test case updated, hope this matches your expectations 👍

Yes that's awesome, thanks 🎉

That's really nice!
