fix: replace compiled files of erc20 contract with right ones

[magicalne]

The original files did not belong to SudtERC20Proxy_UserDefinedDecimals.sol.

Deployment of "solidity/erc20/SudtERC20Proxy_UserDefinedDecimals.ContractCode.hex" fails. Are you able to deploy this contract on Godwoken Testnet v1?

Existing code in https://github.com/nervosnetwork/godwoken-polyjuice/blob/compatibility-breaking-changes/solidity/erc20/SudtERC20Proxy_UserDefinedDecimals.bin is working fine.

You're right. My mistake. I should update the abi file only. Thanks!
