DOCS: main readme has links to old non-existint packs and files

[madeinoz67]

The repos main README still has references to old packs and non existant files / broken links

roadmap also needs reviewing

example:

https://github.com/danielmiessler/Personal_AI_Infrastructure/blob/main/Packs/pai-history-system.md

I confirm. I'm looking where it's been moved.
