Fix tips links
Goal
Currently we have a lot of placeholders in tip "show details" URLs. Upon creating a proper knowledge base we should at least substitute URLs with real good articles.
e.g. https://postgres.ai/#tip-index-inefficient-high-filtered
doesn't work.
TODO / How to implement
- Add basic pages in our docs for Joe recommendations
- Fix links in Joe configs
