[MPIR-402] Modules Report: provide links to Maven Central

**[Florian Brunner](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=puce)** opened **[MPIR-402](https://issues.apache.org/jira/browse/MPIR-402?redirect=false)** and commented

In the table of the modules report also provide the links to Maven Central.

This issue is actually about contributing a patch I made some years ago back to this upstream project.

Here is a sample how it looks like: https://www.drombler.org/drombler-fx/1.0/docs/site/modules.html

I'm using this patch already for several years and it is great for documenting the Maven coordinates of libraries, especially in multi-Module projects, IMHO.

I typically directly point to this report from some prominent places such from a top site inside the documentation (https://www.drombler.org/drombler-fx/1.0/) or in blog posts (https://puces-blog.blogspot.com/2020/01/drombler-fx-version-10-released.html).

Start with the modules report and the Maven Central coordinates it currently displays, then compare the report output with the linked sample at drombler.org. Done means the modules table includes working Maven Central links for the documented libraries, including multi-module projects.
