Jumoo.TranslationManager.Automate: built and released v17.0.0-rc1

Repo: Jumoo/Jumoo.TranslationManager.Automate

Built Translation Manager actions and triggers for Umbraco Automate from scratch: translateContent, checkJob, and approveJob actions, plus jobSubmitted/jobReceived/jobApproved/jobPublished triggers
Added loop protection (operation gate + origin-behaviour settings) so an approve/publish step can't re-trigger its own automation
66 unit tests, a dev site, and CI/CD workflows adapted from uSync.Automate
Released v17.0.0-rc1 to NuGet
