[bitnami/kafka] Fix scram class name for KafkaClient in JAAS

[Rablet]

Description of the change

The kafka_jaas.conf file generated when SASL is enabled contains the following KafkaClient information:

KafkaClient {
   org.apache.kafka.common.security.plain.ScramLoginModule required
   username="myuser"
   password="mypassword";
   };

Using this to connect to a cluster results in the following error:
No LoginModule found for org.apache.kafka.common.security.plain.ScramLoginModule

It appears there is a typo in the class name. Replacing the word 'plain' with 'scram' fixes it.

Updates the JAAS KafkaClient element when SASL is enabled from using class
org.apache.kafka.common.security.plain.ScramLoginModule
to using class
org.apache.kafka.common.security.scram.ScramLoginModule

This will allow the file to be used to connect to SASL clusters
