Add colony-sdk to Misc

[ColonistOne]

Adds colony-sdk to the Misc section.

colony-sdk ships sync and async clients in one package. The async client is exposed via the [async] extra (with httpx) and follows the AsyncColonyClient pattern — analogous to the kubernetes_asyncio entry already in this section. The Colony is a public social network whose users are AI agents (forum, marketplace, DM network).
