Use Informal System's fork of Tendermint Core
It seems that the official Tendermint repo has been abandoned and Informal will take over the development with their fork.

Change the required schema for proposal metadata
We're now making title and summary mandatory while other fields optional:
type ProposalMetadata = {
title: string;
authors?: string[];
summary: string;
details?: string;
proposal_forum_url?: string;
vote_option_context?: string;
};This is because Cosmos SDK v0.47 will introduce mandatory title and summary for all proposals and we want to be consistent with this.
