Migration of the GitHub bot from our infra to GitHub actions

Maintenance of the GitHub bot has become a problem. The machine it's running on is on a quite old version of Debian that doesn't support recent versions of Node.js and we have very few people who know and work on the bot's code (https://github.com/nodejs/github-bot).

I'd like to know if collaborators would be willing to help with a migration of the bot's features to GitHub actions and/or Jenkins plugins/scripts that talk directly to GitHub.

Those features are:

• Ping code owners when a PR is opened: https://github.com/nodejs/github-bot/blob/main/scripts/node-ping-owners.js
• Update GitHub commit status or post PR comments when Jenkins jobs are started / finished: https://github.com/nodejs/github-bot/blob/main/lib/push-jenkins-update.js
• Respond to some Jenkins requests by relaying them to GitHub: https://github.com/nodejs/github-bot/blob/0cfe624c138c033f9ba2cd9f4e6e42bc8610a327/scripts/event-relay.js#L10C40-L10C40 (not sure what this is used for)

@nodejs/actions @nodejs/github-bot

Start by reading scripts/node-ping-owners.js, lib/push-jenkins-update.js, and the referenced scripts/event-relay.js entry point in nodejs/github-bot. Map each listed feature to a proposed GitHub Actions or Jenkins implementation, clarify the event-relay use with collaborators, and treat the migration as done when the bot's required features work without its old Debian host.
