ci: remove GitHub CI — native git.hanzo.ai + cd.hanzo.ai only

This workflow ran on a self-hosted actions-runner-controller pool. ARC is
being decommissioned: CI executes inside git.hanzo.ai (Gitea Actions,
.hanzo/workflows) and delivery is cd.hanzo.ai reconciling the reviewed image
pin in hanzoai/universe. GitHub is a mirror and runs nothing.

Removed rather than repointed — there is no GitHub-side pool to move to, and
leaving it would keep ARC load-bearing.

-# This is similar to the "Pull Translations" workflow, but without the conditional check to allow us to
-# forcefully pull down translations from Crowdin and create a PR regardless if all the translations are fulfilled.
-#
-# Intended to be used when we manually update translations in Crowdin UI and want to pull those down when
-# they already exist.
