chore(repo): adopt vouch with issue based workflow and require for PRs

[ericallam]

Adopting https://github.com/mitchellh/vouch so we can help potential contributors by requiring a conversation before they can submit a PR. Too many contributors have been skipping the conversation part of contributing to an OSS repo and skipping right ahead to submitting PRs

Walkthrough

Adds a contributor vouch system: a new GitHub issue template for vouch requests, a .github/VOUCHED.td file listing vouched contributors, two GitHub Actions workflows (one to check PRs for vouch status and one to manage vouch actions via issue comments), and updates CONTRIBUTING.md with guidance about obtaining vouch status and the automatic closing of PRs from unvouched users.
