cl: fix chiado (#12716)

fixes below error:
```
[DBUG] [11-11|16:37:19.885] Gotten unexpected root got=0xd566eb4ba463ffbfd9bbe503d295cb5f28ba86fa90f700e2f0d7582dbc8a3814 expected=0x3af6a8f94d7d81e513eeb3a94d8ccda9a4d7d3f1de1e38b5e4c12cd6b4496346
```

due to `BeaconBody` `HashSSZ` root hash being inaccurate
it was affected by chain config params that are different in Gnosis as
per
[specs](https://github.com/gnosischain/specs/blob/master/beacon_chain.md)
