bug: false warning in AggOracle

[joanestebanr]

Bug Report

Version > 0.8.1

When aggoracle is created emit a warning even if the values is right:

[AggOracle.EVMSender.EthTxManager.Etherman]
    L1ChainID = 13473

Emit next warning: Incorrect ChainID in aggOracle provided: 13473 expected: 686868

The number that show the warning is not the right value (must be the eth_chainId of the RPC) and the expected is the rollup ChainID

• The field AggOracle.EVMSender.EthTxManager.Etherman.L1ChainID must not be informed because by default is 0 that is autodiscover. In that case emit also a false warning:

Incorrect ChainID in aggOracle provided: 0 expected: 686868

Proposed solution

• Remove this warning because doesn't have any sense, if we want to check this value we have to add a warning in the library zkevm_ethtx_manager (may be it's already there)
• Encourage to don't set this value in config file because by default is auto-configured
