Add new CI workflows for release and sync tests

[pablomendezroyo]

Introduce new continuous integration workflows for release and execution client sync tests while removing outdated workflows. This update enhances the testing and deployment process.

✅ 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.
