simulator: Fix Failed to initialize dependency logging (#7393)

Browse Source 
The simulator works but always emits the following message:

```
$ cargo run --release --bin simulator basic-sim
...
...
Failed to initialize dependency logging: attempted to set a logger after the logging system was already initialized
...
...
```


  This PR removes the initialization with `env_logger`.

(Update)
With https://github.com/sigp/lighthouse/pull/7433 merged, the libp2p/discv5 logs are saved in separate files and respect the `RUST_LOG` env var for log level configuration.
