serialize decorators don't work without info

[samuelcolvin]

If you try to use the following

class WithCustomEncoders(BaseModel):
    dt: datetime

    @serializer('dt')
    def serialize_dt(self, dt: datetime):
        return dt.timestamp()

You get an error about SerializationInfo doesn't have a timestamp() method.

If you change the signature to def serialize_dt(self, dt: datetime, info):, it works fine.
