Upgrade kinesis client to v3.5.0.

[oermolaev]

• Kinesis client library is set to 3.5.1 version. This way, for direct 2.x -> 3.5 migrations, single DynamoDB table format is
  used from day one, elimination the need for complex schema migrations.
• Modules are affected by this update: kinesis and eventbridge
• A new input config field, clientVersionConfig, was added to Input.Kinesis and mulules application.conf.
• Compatibility with 2.x client is set by default (COMPATIBLE_WITH_2X_PHASE1)
• Tests updated
• Migration documentation added; infrastructure update notes & checklist included

Pull request overview

Updates the Snowplow Enrich Kinesis/EventBridge modules to use amazon-kinesis-client 3.5.0 (and a newer AWS SDK), introducing a new input setting to control KCL 2.x→3.x migration compatibility mode and wiring that through to the KCL scheduler configuration. This aligns the codebase with KCL 3.5’s single-table migration behavior and documents the operational rollout steps.

Changes:

• Bump amazon-kinesis-client to 3.5.0 (and AWS SDK to 2.47.5).
• Add clientVersionConfig to Input.Kinesis config model, config templates, and module application.conf.
• Wire clientVersionConfig into KCL CoordinatorConfig and update unit/integration tests and add a migration guide.
