Add workflow to retrigger translation on PR approval (#625)

Closes the gap where first-time contributor PRs require maintainer
approval, but approval events don't trigger the translation workflow.

New workflow: sync_docs_on_approval.yml
- Listens to pull_request_review (submitted, approved)
- Re-runs the most recent Analyze workflow for the PR
- This triggers the existing Execute chain with fresh artifacts
- Posts "approval received" comment before starting

Note: Fork/author/reviewer checks are commented out for testing.
Search for "TODO: UNCOMMENT" to restore after testing.

### First-Time Contributor Approval Flow
For PRs from forks by contributors who are not OWNER/MEMBER/COLLABORATOR:
1. **PR opened** → Analyze workflow runs → Execute workflow checks for approval
2. **No approval found** → Execute skips translation, posts "pending approval" comment
3. **Maintainer approves PR**`sync_docs_on_approval.yml` triggers automatically
4. **"Approval received" comment posted** → Analyze workflow re-runs with fresh artifacts
5. **Execute workflow runs** → Finds approval → Creates translation PR
**Approval requirements**:
- Reviewer must have OWNER, MEMBER, or COLLABORATOR association
- Approval triggers immediate translation (no additional push needed)
- Each approval posts a new comment preserving the timeline
**Edge cases**:
- If translation PR already exists when approval happens → info comment posted, no re-run
- If Analyze run is too old to re-run → error comment with instructions to push a small commit
- Internal PRs (same repo, not fork) → no approval gate, auto-translates immediately
**Manual trigger**: If approval flow fails, maintainers can manually trigger via Actions → Execute Documentation Sync → Run workflow (enter PR number)

**Approval flow issues** (first-time contributors):
- **Translation not starting after approval**: Check Actions tab for `Retrigger Sync on Approval` workflow status
- **"Could not automatically start translation"**: Analyze run too old - push a small commit to trigger fresh workflow
- **Approval from non-maintainer**: Only OWNER/MEMBER/COLLABORATOR approvals unlock the gate
- **Multiple "pending approval" comments**: Normal - each commit triggers Execute which posts if no approval found
