Describe the bug

https://github.com/aws-amplify/amplify-android/blob/6bbb8c466e274caee8dca674d1acb6e8cbe5e372/aws-predictions/src/main/java/com/amplifyframework/predictions/aws/http/LivenessWebSocket.kt#L475

videoEndTimestamp ends up being the start time of the last video chunk containing data. This last video chunk could range from 0-1 seconds of content, resulting in the timestamp being off. This value is only used for metrics, and does not impact the challenge, as the actual end is determined by sending the empty video event.

For metric purposes, we should look to adjust this timestamp to be the proper end time.
