License metadata issues

[Kyle-Neale]

Description

We have license validations we perform on dependencies we're shipping and confluent-kafka-python has changed. The license metadata looks bungled going from 2.6.0 to 2.6.1.

• https://pypi.org/project/confluent-kafka/2.6.0/
• https://pypi.org/project/confluent-kafka/2.6.1/

How to reproduce

N/A

Checklist

Please provide the following information:

• confluent-kafka-python and librdkafka version (confluent_kafka.version() and confluent_kafka.libversion()):
