Docs are out of sync

In my spare time I am having a fresh look at cardaminal and try to play with it, but documentation is outdated and I am not even able to create a chain!
I am trying to do the following:

```
% cardaminal chain create mainnet 764824073 relays-new.cardano-mainnet.iohk.io:3001 1
2024-09-11T06:28:12.682533Z INFO create{name="mainnet"}: cardaminal::chain::create: chain created chain="mainnet"
```

then

```
% cardaminal chain sync mainnet
2024-09-11T06:28:24.067792Z INFO sync{name="mainnet"}: cardaminal::chain::sync: updating chain="mainnet"
2024-09-11T06:28:24.080399Z INFO sync{name="mainnet"}: cardaminal::chain::upstream: intersecting chain points=[]
Error: × invalid digit found in string
```

The documentation does not have this `ADDRESS_NETWORK_ID` parameter, what does this represent?
