Integrate op-erigon into op-e2e as an external L2 client

[ImTei]

This should be an issue of the optimism monorepo, but making it in this repo for tracking purpose.

Hive was the project to test functionality and compatibility of OP stack execution/consensus(rollup) clients, but it was deprecated and replaced with op-e2e in the monorepo.

op-e2e has an example of using external client for test: external_geth. So we should add op-erigon into op-e2e and replace our hive.
