feat: adding comment field in clauses

[Valazan]

This PR adds support for the comment field when transacting with the contract module:

await contract.transact.transfer(
    { comment: 'Transferring 100 ERC20 tokens' },
    '0x9e7911de289c3c856ce7f421034f66b6cde49c39',
    unitsUtils.parseUnits('100', decimals[0] as bigint)
);

Or when building clauses:

const clauseSet1 = loadedContract.clause.set(
            {
                comment: 'set the value in the contract to 123'
            },
            123n
        );
