fix: Revert 2d1c64f ("Handle JSON numbers as Decimal not float")

1e9999 causes ValueError: "Exceeds the limit (4300) for integer string conversion; use sys.set_int_max_str_digits() to increase the limit"

cove-ocds, to my knowledge, doesn't perform arithmetic on floats, and in any case, it is a review tool, not a statistical tool.
