fix(ci): generate i18n data before hetzner reaper

[lalalune]

Summary

• add the shared i18n/codegen step to the Hetzner E2E Reaper workflow before it imports @elizaos/core through the cloud shared client
• fixes the active scheduled reaper failure where bun install --ignore-scripts leaves packages/core/src/i18n/generated/validation-keyword-data.ts absent

Fixes part of #14051.

Evidence

• Active failed run: https://github.com/elizaOS/eliza/actions/runs/28979847696 failed in Reap with Cannot find module ./generated/validation-keyword-data.ts.
• Local reproduction after this patch: node packages/app-core/scripts/ensure-shared-i18n-data.mjs && HCLOUD_TOKEN_CI= bun run packages/scripts/cloud/admin/hetzner-e2e/hetzner-e2e-reaper.ts reaches [hetzner-e2e-reaper] HCLOUD_TOKEN_CI not set; skipping instead of crashing during import.
• ruby -e 'require "yaml"; YAML.load_file(".github/workflows/hetzner-e2e-reaper.yml"); puts "hetzner-e2e-reaper.yml parsed"' passed.\n- actionlint .github/workflows/hetzner-e2e-reaper.yml passed.\n- git diff --check passed.\n\n## Evidence Checklist\n\n| Required evidence | Status | Notes |\n| --- | --- | --- |\n| Tests / commands | Done | Workflow parse, actionlint, local no-token reaper smoke, diff check. |\n| Backend logs | N/A | Workflow-only CI fix; no application backend path. |\n| Frontend screenshots/video | N/A | No UI change. |\n| Real-LLM trajectories | N/A | No agent/model behavior change. |\n| Domain artifacts | N/A | No cloud deletion executed locally because HCLOUD_TOKEN_CI is intentionally unset. |\n
