withdraw from OKX to Arbitrum failed

• OS: Windows 10
• Programming Language version: Python
• CCXT version: 2.4.49

exchange.withdraw(
                token, amount, to_address,  params={
                    "network": "Arbitrum one"
                    "fee": self.withdraw_fee,
                    "pwd": ""
                }

here safe_string_upper caused this error, OKX need exactly "Arbitrum one" to be the network to withdraw, but ccxt convert all to upper string, so as returned "Parameter chainName error"

Hi @eliiik

Thanks, looks like the code also broken for Avalanche / Optimism. We'll fix asap.
