Kafka Scaler- brokerlist should be removed from the example in document

[Ritikaa96]

A clear and concise description of what the bug is.

As per : kedacore/keda#882
brokerList for Kafka Scaler has been deprecated.
we can see it's mention on the example for metadata here: https://keda.sh/docs/2.4/scalers/apache-kafka/#trigger-specification

As this has been deprecated since v1.3 earliest, can we remove the mention now as not to confuse the user?

Expected Behavior

brokerList should not be mentioned anymore.

Actual Behavior

we can see the mention here: https://keda.sh/docs/2.4/scalers/apache-kafka/#trigger-specification

Steps to Reproduce the Problem

1. go to https://keda.sh/docs/2.4/scalers/apache-kafka/#trigger-specification
2. check out the metadata.

Specifications

• KEDA Version: any
• Platform & Version: any
• Kubernetes Version: 1.20.2
• Scaler(s): Apache Kafka

@tomkerkhove @zroubalik @ahmelsayed let me know what you think.

Good catch, if I am not mistaken it should be removed from all 2.x versions of docs.

@zroubalik Yes, we can see the v2.0.0 release notes, the deprecation is mentioned in breaking changes for kafka.
