Broken third party links to deleted website resources

[libremente]

Describe the bug

Unfortunately, after #1136, some third party links pointing to that resource are now broken (see this as an example https://cloud-pa.readthedocs.io/projects/SaaS/it/latest/#comunita). We should find a way to correctly render the "communities" inside the Developers Italia page, I don't think the "Platform" section is the way to go.

Even worse, that link is inside some official PDF files, see this one https://www.agid.gov.it/sites/default/files/repository_files/manuale_di_abilitazione_al_cloud_11pt_id2.pdf

I think we should revert then! @libremente wdyt?
