🔹[EPIC] Migrate wiki.near.org to docs

[bucanero]

Description

wiki.near.org needs to be deprecated and useful technical content migrated to docs.near.org

---

Goal

From Illia's feedback:

Let’s merge content and remove it. It never became a community type thing as initially planned. It will make sense to just have more content pages on near.org later but most should go to docs.
