Change the threshold to put a proposal on-chain from the current 2 votes to 1 vote.

Why:

• We are disenfranchising roughly 80% of noun holders currently.
• We are not seeing many proposals coming in.
• We want to empower any nouner or delegate to participate in the DAO.

Setting the proposal threshold to 1 would require 2 votes again once we passed 9999 nouns in roughly 26 years.
