Create auction example argv naming on README.md is not the expected one by the script

[alfonsoegio]

README example (not working):

npm run create-auction -- --owner_pvk '0xd2827f4c3778758eb51719a698464aaffd10a5c7cf816c1de83c5e446bfc8e8d' --currency_id 0 --auction_price 345 --auction_rnd 12342234 --valid_until '1632395810' --time_to_pay '172800' --asset_id '36771977682424071759165601888702044610709221343463'

Proper command (working):

npm run create-auction -- --pvk '0xd2827f4c3778758eb51719a698464aaffd10a5c7cf816c1de83c5e446bfc8e8d' --currencyId 0 --price 345 --rnd 12342234 --timeValidUntil '1632395810' --timeToPay '172800' --assetId '36771977682424071759165601888702044610709221343463'
