CTF challenge from docs is broken

[VIELITE]

When running ItyFuzz against an on-chain deployed CTF, I encountered the following error:

thread 'main' panicked at src/evm/onchain/endpoints.rs:791:29:
fail to get block timestamp
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace```

Seems to be a connectivity issue with the public RPCs. You can use ETH_RPC_URL=https://xxx ityfuzz ... to specify the RPC you would like to use. We recommend using Infura or Quicknode
