Our basic sim test has been [flaky](https://github.com/sigp/lighthouse/actions/runs/15458818777/job/43515966229) for some time, and seems like it has gotten worse since electra fork was added to it in #7199. It looks like the github runner is struggling with the load, currently it runs 7 nodes on a 4 CPU runner, which is definitely too much. We could consider moving this to run on our self hosted runner - but I think running 7 nodes is unnecessary and we can probably trim test this down. Reduce number of basic sim test nodes from 7 (3 BN + 3 Proposer BN + 1 extra) to 4 (2 BN + 1 Proposer BN + 1 extra). If we want to run more nodes, we'd have to consider running on self hosted runners.
