List the public bases you follow.

Requires a personal account or personal API key. Following grants no private access. Up to 50 hosted public bases per account. Updates show the latest published version of each document, not a version history. Repeated publication of the same version creates no update. Each read checks current publication. Unfollowing removes all notices for that base. Responses use private, no-store. No email or push messages. Returns: { items[{id,name,available,followed_at,public_url}], total, limit }
