blocklist import/export

首先检查 cutenode/action-import-blocklist，以及为 pkgjs、nodejs-private 或 nodejs 提议的 .github 仓库和工作流。在实现之前解决 ownership、PAT admin:org、调度和 username-logging 相关的问题。当三个组织之间通过一个已达成共识的项目拥有的工作流同步 blocklist 时，即视为完成。

per the recent discussion around the moderation team and importing/exporting the blocklist across our three orgs (nodejs, pkgjs, and nodejs-private), I went ahead and built out a GitHub Action that allows us to import blocklists from one organization to another organization. In practice, this means that if someone is blocked in the nodejs org, that block can be imported to the other organizations automatically (presumably on a cron or manual run of the Action, rather than being directly triggered by the block event).

You can find the code in cutenode/action-import-blocklist. Implementing it requires a PAT from an account (presumably, in our case, the Node.js bot account) that has the full admin:org permissions, which is required by the GitHub API.

@nodejs/tsc @nodejs/actions want to get feedback on this. My proposal:

• implement syncing to pkgjs and nodejs-private by setting up .github repositories in both and adding workflows. I'm happy to help with this, but it's pretty trivial.
• alternatively, implement syncing by setting up a .github repo in the nodejs org, allowing us to have control within the project of where our blocklist is being exported to and not providing admin:org tokens to those orgs (pkgjs is notably more permissive).

questions I have:

• currently, the Action uses console.log() to output what's happening. This does include usernames. Is this okay, or would we want to omit those?
• I'd prefer to move the action to a project-owned organization. Does this belong under nodejs or under pkgjs?
