Decouple hypergraph repo from hypergraph documentation repo

[pranavdaa]

Remove documentation and make it independent of the main hyper-graph repository to not have too many commits in just one repo with major changes

sounds good 👍

After some discussion https://geo-browser.slack.com/archives/C069PB8PCPN/p1755580724633419?thread_ts=1754938067.854959&cid=C069PB8PCPN we decided to keep it in here

Benefits:

• We can auto-generate the API docs easily
• We can keep track of docs updates with feature development
