chores: update pascal-hardfork contracts repo commit id

This PR tries to improve https://github.com/bnb-chain/bsc/pull/2680
If the node did not set `Eth.Miner` in config.toml, the default GasCeil
will be 30000000, it is not an accurate number for both BSC mainnet and testnet.
Set it to 0 means disable the transaction GasLimit check, i.e. the TxPool will
accept transactions with any GasLimit size.
