Documentation error: UpdateItem sample request expected condition incorrect

[Charles Wang]

The sample request for UpdateItem API is incorrect in the expected condition part.

Right now, only "value" and "exists" are supported but the sample request has the following expected condition:

    "expected": {
        "LastPostedBy": {
            "comparison_operator": "EQ",
            "attribute_value_list": [
                {
                    "S": "<email address hidden>"
                }
            ]
        }
    },
