ci: add Discord notification to sync workflow

[Copilot]

Adds Discord notification job to the sync workflow, matching the implementation already deployed in the Geth generic repository.

Changes

• Added notify job to .github/workflows/sync.yml that triggers on sync completion (success, failure, or cancellation)
• Uses reusable workflow dappnode/staker-test-util/.github/workflows/notify-discord.yml@main
• Configured with test_type: "sync" and inherits repository secrets

  notify:
    needs: sync
    if: always() && needs.sync.result != 'skipped'
    uses: dappnode/staker-test-util/.github/workflows/notify-discord.yml@main
    with:
      result: ${{ needs.sync.result }}
      test_type: "sync"
    secrets: inherit

Original prompt

Context

A change was already implemented in the Geth generic repo that adds a Discord notification job to the sync workflow:
dappnode/DAppNodePackage-geth-generic@7552d5b

This same change needs to be applied to this repository.

Task

Add a new notify job at the END of the .github/workflows/sync.yml file.

The job to add is:

  notify:
    needs: sync
    if: always() && needs.sync.result != 'skipped'
    uses: dappnode/staker-test-util/.github/workflows/notify-discord.yml@main
    with:
      result: ${{ needs.sync.result }}
      test_type: "sync"
    secrets: inherit

Requirements

1. Open the file .github/workflows/sync.yml
2. Add the notify job at the END of the workflow file (after all existing jobs)
3. Do NOT modify any other jobs
4. Do NOT refactor workflow formatting
5. Do NOT reorder existing jobs
6. The notify job must depend on sync
7. Ensure indentation remains valid YAML

Branch and Commit

• Create branch: add-sync-notify-job
• Commit message: ci: add discord notify job to sync workflow
• Open PR to main
• Do NOT merge the PR

✅ SYNC TEST REPORT - PASSED

This CI runs on a real DAppNode using the same RPC calls a user would make to configure a staker setup: execution client, consensus client, web3signer, MEV-boost, and relays. The self-hosted runner is pre-loaded with synced (or near-synced) execution client volumes, enabling fast sync and attestation tests with any client combination. Consensus clients use checkpoint sync, so no pre-synced volume is required.

Sync Test: Verifies that both execution and consensus clients reach a synced state. This test ensures the staker configuration is valid and clients can synchronize with the network.
