Describe the bug

I want to have both evm.gasEstimates and evm.methodIdentifiers as extra output when compile my project.
I can do it by adding extra_output = ["evm.gasEstimates", "evm.methodIdentifiers"] in foundry.toml.
But it seems I cannot do it by using forge build --extra-output="evm.gasEstimates","evm.methodIdentifiers"

thanks for flagging, this should be fixed easily, probably something's off with the args parser settings here
