feat(Governance): Restrict Core Governance To Humans

[JayWelsh]

Restricts the following functions to Humans:

deposit(uint amount)
propose(address target, bytes memory data)
proposeWithFeeRecipient(address feeRecipient, address target, bytes memory data)
voteYes(uint proposalId)
voteNo(uint proposalId)
finalize(uint proposalId)

Also does restricts Humans from voting both yes and no

Just putting this out there for the purpose of opening the potential opportunity for a discussion surrounding this on GitHub.
