Fix geth scripts (#4342)

## Issue Addressed

N/A

## Proposed Changes

Geth's latest release breaks our CI with the following message
```
Fatal: Failed to register the Ethereum service: ethash is only supported as a historical component of already merged networks
Shutting down
```
Latest geth version has removed support for PoW networks. Hence, we need to add an extra `terminalTotalDifficultyPassed ` parameter in the genesis config to start from a merged network.
