[BUG] Disabling and Enabling DynamoDB streams requires a restart of Data Prepper

[graytaylor0]

Describe the bug
If I disable and enable the streams on my DynamoDB table, Data Prepper will continue looking for the old stream ARN that does not exist, and does not do a rediscovery of the stream ARN.

To Reproduce
Steps to reproduce the behavior:

1. Start a DynamoDB pipeline reading from streams
2. Disable and re-enable DynamoDB streams on the table
3. Observe the error from Data Prepper that the stream does not exist

Expected behavior
Data Prepper could gracefully handle the case where the stream does not exist, and rediscover the new Stream ARN

Additional context
Add any other context about the problem here.

@graytaylor0 , Can you include the error that you see? That might help with providing the resolution.
