Update audit event streaming docs
Problem
Currently the Audit Event Streaming page contains sections on how to add, edit and delete destinations through the UI. There is then sub sections for the different types (group, instance, GCP Logging). As we add more types this will become more unwieldy then it already is. This is replicated in the GraphQL API docs
Proposed solution
Improve the Audit Event Streaming structure to allow for better reading.
