Fix failure when replaying block number 21041283

[Wodann]

Block number 21041283 is failing to replay correctly (ci failure, Repro branch).

Potentially related: erigontech/erigon#12242

Analysis

One transaction in the block reverts instead of succeeding, with this error message:

EigenPod.getParentBlockRoot: invalid block root returned

It might be that we're not correctly setting the parent_beacon_block_root (EIP-4788)

Definition of done
Fix the bug such that the test in the repro branch succeeds.

This is still ongoing, see also #github-action-notifications.
Recent ci failure for block 21556935. This also has a parent_beacon_block_root, so it seems related.

For block 21554554 (also a CI failure), there's definitely a transaction that interacts with the beacon block root contract, this one: https://etherscan.io/tx/0x39a54a342dc91209f8a0533b20ca2195b774f576e6f47dacd27fcdeb3edd3985

If you go to the "Internal Txns" tab and enable advanced mode, you'll see that the last internal transaction is a static call to 0x000F3df6D732807Ef1319fB7B8bB8522d0Beac02 (the address of the beacon block root contract).
