WARN deprecated: .Site.DisqusShortname was deprecated in Hugo v0.120.0

Reason/Context

The latest Hugo version (well, since 1.120.0, which was released on Oct 30, 2023) reports this deprecated issue:

WARN deprecated: .Site.DisqusShortname was deprecated in Hugo v0.120.0 and will be removed in a future release. Use .Site.Config.Services.Disqus.Shortname instead.

Description

This is not a critical update, but it is good to manage it up front and not wait for it to be decommissioned, as we rely on Disqus for the website blog post comments.

Implementation ideas

Based on Hugo's documentation:
https://gohugo.io/methods/site/disqusshortname/
https://gohugo.io/methods/site/config/

I have tested this simple update locally:

% diff themes/microcks/layouts/_default/single.html themes/microcks/layouts/_default/single.html.PATCHED
34c34
<         {{ if site.DisqusShortname }}
---
>         {{ if .Site.Config.Services.Disqus.Shortname }}

And it should work. No more WARN was reported when using Hugo. But need to be tested on the deployed site as:

LGTM. You can commit this and I'll deploy a new version of the website.
