Pull request overview

This PR adds a third e2e test configuration to the workflow that tests op-reth running in both the sequencer and verifier positions simultaneously, complementing the existing tests where op-reth runs only as verifier (with op-geth as sequencer) or only as sequencer (with op-geth as verifier).

Changes:

• Added new op-reth-as-sequencer-and-verifier job that runs e2e tests with op-reth in both roles
• Updated the success check job to include the new test configuration as a dependency
