New Substrate docs do not contain the SS58 spec & details.

[nuke-web3]

https://github.com/substrate-developer-hub/substrate-docs/blob/archive/main-mdx/v3/docs/07-advanced/h-ss58/index.mdx is the now non-existent file on main.

AFAIK there is now no hosted details on how SS58 works in detail.... where should this content live?

• In this repo?
• In a wiki for this repo?
• In a new place on docs?
• Other?
