Suggestion: auto-land and auto-release NCU Pull Requests

Looking at our Pull Requests list, seems like we have six pull requests ready to land (with approvals), but I don't think it's clear who is allowed to land PRs in this repository. Similarly, sometimes commits will sit on master for a while until someone has time to publish a new version on npm. My suggestions:

1. A scheduled GitHub Action that will merge all PRs with at least one approval and green CI. This could run every 5 minutes (quickest the scheduler can run), or maybe every hour (since we don't have a big flow of PRs here).
2. A scheduled GitHub Action that will make a new release to npm every day (if we want quick releases) or every week (if we want slower releases)

We would need to identify semverness of PRs somehow, either via labels or using https://www.conventionalcommits.org/en/v1.0.0/. Looking at our logs, we're already not strictly following Node.js core commit guidelines and we have mixed Node.js and conventional commit messages.

As for npm releases, it might be tricky because we require 2FA. If anyone worked with 2FA and automated npm releases before, I'd be happy to see solutions :)

まず、リポジトリに既存する GitHub Actions と npm の公開設定を確認し、その後、提案されている承認、CI、semver、スケジューリング、2FA の要件を比較します。完了とするには、実装の範囲を定める前に、合意された自動化およびリリースポリシーが必要です。
