Juan is now a Github Org owner

[bmann]

@bumblefudge is now an owner of the https://github.com/ChainAgnostic org, joining @pedrouid and @ligi. This is to unblock him from assisting in day to day operational tasks, like repo access permissions and other settings.

We should further document various things around teams, and look at creating bots for various things. This might be a use of funds.
