[Flow EVM] Validation of error message on transaction replay is broken

[m-Peter]

The following 2 PRs:

• Include human-friendly error messages on EVM transaction events #6836
• Use ErrorMessageWithRevertReason when validating replay of EVM tx #6952

improved the errorMessage field of the EVM.TransactionExecuted payload, to also include any revert reason, if present.

However, the validation of transaction replay logic is sensitive to this, as it performs a strict check on the actual error message (https://github.com/onflow/flow-go/blob/master/fvm/evm/offchain/sync/replay.go#L168-L171).

We can improve this validation check, by simply checking the errorCode field, which is unlikely to change, like the errorMessage content.
