Only use authenticated endpoints during EE integration testing (#3253)

## Issue Addressed

Failures in our CI integration tests for Geth.

## Proposed Changes

Only connect to the authenticated execution endpoints during execution tests.
This is necessary now that it is impossible to connect to the `engine` api on an unauthenticated endpoint.
See https://github.com/ethereum/go-ethereum/pull/24997

## Additional Info

As these tests break semi-regularly, I have kept logs enabled to ease future debugging.
I've also updated the Nethermind tests, although these weren't broken. This should future-proof us if Nethermind decides to follow suit with Geth
