Current chainspec is failing to archive sync using Nethermind's client 

Current chainspec is failing to sync using NM client, as it doesn't provide a value for 'maxCodeSizeTransition' and NM client expects one.
```diff
   "params": {
        "networkID": "0xF6",
        ...,
        "maxCodeSize": "0x6000",
+       "maxCodeSizeTransition": "0x0",
        ....
    },
```
