Replace deprecated commitRecord method to support Kafka 4.0

[Adil9645]

Description

This Pull Request updates the usage of the deprecated commitRecord method to the new method introduced in Kafka 4.0.

The method signature:
public void commitRecord(final SourceRecord record) throws InterruptedException

has been replaced with:
public void commitRecord(final SourceRecord record, final RecordMetadata metadata) throws InterruptedException

All usages of the old method have been updated accordingly. For example:
newConnectTask.commitRecord(kafkaMessage);

has been changed to:
newConnectTask.commitRecord(kafkaMessage, null);

This ensures compatibility with Kafka 4.0 while maintaining existing functionality.
