Drop AWS SDK v1 Support

AWS is killing support for the V1 SDK at the end of Jan

AWS themselves have been VERY slow to remove SDK v1 support in their Kinesis producer and client libraries.

The kinesis-producer-library was only just released with v2 support in dec '24, which makes their SDK deprecation timeline a bit disappointing.

The kinesis-client library dropped v1 only in nov '24.

It appears that AWS have no intention of supporting DynamoDB event streams via the SDK, as there has been next to zero development on the adapter code.

I propose that we move to the latest versions of the kinesis producer and client, effectively removing any transient dependency on the v1 SDK. This means however that all DynamoDB streaming support in this library will have to be dropped, with folks following AWS's recommendation and moving to native dynamodb->kinesis event streaming.

This will be a major breaking change in fs2-aws, and will necessitate a major release.
