Remove amazon-kinesis-client dependency override

[jamesnetherton]

Quarkus 3.29 upgrades protobuf-java to 4.x, so we need a newer amazon-kinesis-client to stay compatible.

We previously held back the upgrade in the Camel core, so we'll need to unblock that to remove the workaround in this project.

+1, do you have a target version for amazon-kinesis-client?

[jamesnetherton]

I've aligned to the latest 3.1.3.

Also opened apache/camel#19458.
