Jimmy Chen 5cd738c882 Use unique arg names for eth1-sim (#4463)
## Issue Addressed

When trying to run `eth1-sim` locally, the simulator doesn't start for me, and panicked due to duplicate arg names for `proposer-nodes` (using same arg names as `nodes`). Not sure why this isn't failing on CI but failing on mine 🤔 

```
thread 'main' panicked at 'Argument short must be unique
thread 'main' panicked at 'Argument long must be unique
```
