What is the issue?

All Addtional Resources-pages contain older content, many of which are not compatible with v5. The projects-page has a compatibility note about this, but the others don't.

Suggested fix?

Search and add newer content compatible with v5

Remove or mark content compatible with Pester v5. Marking could be done using either a column like "Compatible with", "Created for" etc. OR move older content to a summary/details group so users can explore. The articles can often be valid for ideas/concepts.

Totally agree but I would follow a more destructive route here. Perhaps a single page/table with only actual resources would be better.
